An indoor range is equipped zone by zone. The zone split used here comes from the Estonian defence requirements RKIK Annex 2 (05.11.2025, point 26), a procurement document, not an EU rule: a safe zone behind the firing points, an intermediate zone, and a protection zone with the bullet trap, the steel plate behind it and the back wall. Forward of the firing line, walls, ceiling and floor must be bullet-resistant and must not ricochet. BulletTrap Baltic supplies the ballistic part: bullet traps, anti-ricochet lining, clearing barrels and targets.
Which rules apply to an indoor shooting range in Europe?
Range requirements are national: Estonia, Latvia, Germany and Poland each publish their own, and the ISSF rule book adds competition dimensions on top.
The documents used on this page, and what each one covers:
- Estonia: Regulation No. 39 of the Minister of the Interior of 05.10.2026, in force since 10.10.2026, replaced Regulation No. 12 of 2021. Ranges built before it with the written consent of the local government must comply by 31.12.2027 (§ 31(2)). For the detail of an indoor hall the most complete text is RKIK Annex 2 «Siselasketiirude nõuded» (Estonian Centre for Defence Investments), the requirements for the ranges it procures; the document does not state that it applies to private ranges.
- Latvia: Cabinet Regulation No. 494 of 28.07.2020. It sets the principles and leaves noise and wall thickness to building and building-acoustics regulations (point 2).
- Germany: the Schießstandrichtlinien of 23.07.2012 (BAnz AT 23.10.2012 B2), which § 27a(3) of the Weapons Act (WaffG) requires to be applied in their current version.
- Poland: Dz.U. 2022 poz. 848, a regulation of the Minister of the Interior and Administration of 31.03.2022. It applies only to the indoor ranges of the Police, Border Guard and State Protection Service.
- Lithuania: the requirements are set by a Lithuanian police order; check which text is in force in the Register of Legal Acts (e-TAR) before design.
- ISSF Rule Book 2026 (Edition 2025, third print 10/2026), General Technical Rules 6.4: distances, target heights and lighting for competition ranges.
What are the zones of an indoor shooting range?
RKIK Annex 2 names three zones, numbered from the target end: zone I takes most of the hits, zone II may be hit, zone III behind the firing points stays safe.
Zone III · Safe zone
Behind the firing position (point 26 a). ISSF separates spectators by a barrier at least 7.0 m behind the firing line (GTR 6.4.3.4).
Zone II · Intermediate
Between the firing line and the trap, where structures can be hit (point 26 b). Lining on walls, ceiling and floor; protruding parts allowed only as deflector plates and baffles (point 7).
Zone I · Protection zone
Where most bullets land, with the highest risk of ricochet and fragments (point 26 c). It contains the bullet trap, the steel plate behind the trap and the back wall.
Poland describes the same end of the range in three parts for its police ranges: a ricochet absorber, a projectile catcher for recovery and recycling, and the bullet trap proper (Dz.U. 2022/848, § 19(1)).
Indoor shooting range equipment by zone
Every piece of equipment in a zone has a clause behind it. The table gives the clause and what BulletTrap Baltic supplies for it.
| Zone | Equipment | What the norm requires (document, point) | What BulletTrap Baltic supplies |
|---|---|---|---|
| III · Safe zone | Entrance, clearing area, spectator barrier | Entry through double doors (RKIK Annex 2, 131 c). Door with a burglar-resistant lock, fire alarm, entry to the danger zone locked from inside (Latvia No. 494, 7.2–7.4). Spectator barrier at least 7.0 m behind the firing line (ISSF GTR 6.4.3.4). The clearing area is not covered by the clauses cited on this page | Bullet Crusher clearing barrels BC-1, BC-2 ARMY, BC-1 Tactical, BC-1 Pistol; stands ST 12 and HST 12 |
| Firing line | Screens between firing points, floor at the firing line | Transparent screens: 0.75 m forward and 0.25 m back of the firing line, at least 1.7 m long, top edge at least 2.0 m above the floor (RKIK 27 c). Even floor at the firing line (Latvia No. 494, 7.11). Floor with a ricochet-resistant construction over the whole length of the range (RKIK 48) | Anti-ricochet tiles BRT-40 / BRT-45 for the floor |
| II · Intermediate | Wall and ceiling lining, baffles, protection for lights and ventilation | Walls, ceiling and floor bullet-resistant; walls covered with at least 1.2 cm of non-ricocheting material, or hits on the wall excluded by deflector plates (Estonia No. 39, § 12(1)–(2)). No protruding parts except deflector plates and baffles (RKIK 7). Lights recessed or shielded (RKIK 15); ventilation elements forward of the firing line protected (RKIK 77) | Anti-ricochet tiles BRT-40 / BRT-45 for walls, ceiling and baffle faces |
| I · Protection zone | Bullet trap, steel plate behind it, back wall, targets | Trap material, thickness and properties must ensure all bullets are received (Estonia No. 39, § 12(5)). Trap on its own foundation, not rigidly fixed to the load-bearing structure (RKIK 127 c). Trap fully neutralises kinetic energy and excludes ricochet (Latvia No. 494, 5.4). A serial trap system is type-tested with at least 10,000 shots per trajectory (Germany, 2.8.4) | Bullet trap of 200 mm BRB-200 blocks in front of a 500 HB armoured plate, configured per project; steel and moving target systems |
| Openings | Doors, windows, issue hatches | In a new range, doors and windows only behind the firing line, in the side wall; windows only behind the firing line (RKIK 55, 64). No windows in the range hall (Latvia No. 494, 7.7). Windows non-opening, bullet-resistance class matched to the highest bullet energy (Poland, § 13, § 23(3)) | Ballistic roller shutters, made to order in Lithuania, EN 1522 class to specification |
| Whole hall | Ventilation, lighting, acoustics, fire safety | Forced ventilation only (RKIK 66). Target lighting at least 1,000 lx at 25 m and 2,000 lx at 50 m (RKIK 108). Reverberation time at most 1.0–1.5 s, 500–2,000 Hz (RKIK 128 a). Separate fire compartment, EI30, two exits (RKIK 11, 139, 142) | Specified by the project’s building-services designers; BulletTrap Baltic fits the trap and lining around them |
The rows combine documents of different countries. They are not cumulative: apply the document that governs the site. Whether a lining or shutter meets a rule is decided for the project by the range expert or the authority; the shutter class is confirmed in the quote. The product overview by zone, including outdoor ranges and mobile test ranges, is on the shooting range equipment hub.
How long and how high must an indoor range be?
RKIK Annex 2 asks for the shooting distance plus 5 m of hall length and 2.20 m of clear height; Latvia asks for at least 2 m of ceiling height.
| Dimension | Requirement | Document, point |
|---|---|---|
| Hall length | Shooting distance + 5 m for firing points and the trap; distance measured from the farthest firing line to the target | RKIK Annex 2, 18 |
| Recommended distances | 10, 15, 25 or 50 m | RKIK Annex 2, 28 |
| Distance tolerance | 10 m ±0.05 m; 25 m ±0.10 m; 50 m ±0.20 m, from the firing line to the target face | ISSF GTR 6.4.5.1–6.4.5.2 (RKIK 29 has the same 25 and 50 m values) |
| Clear height | At least 2.20 m including protective elements; baffles mounted high enough to keep it | RKIK Annex 2, 19 and 41 |
| Ceiling height | At least 2 m (3 m where the bow or crossbow shooting distance exceeds 3 m) | Latvia No. 494, 7.6 and 8.4 |
| Hall height, police ranges | At least 3.3 m; at least 2.5 m in reconstructed buildings | Poland Dz.U. 2022/848, § 8 |
| Target centre height | 10 m: 1.40 m ±0.05 m; 25 m: 1.40 m (+0.10/−0.20 m); 50 m: 0.75 m ±0.50 m | ISSF GTR 6.4.6.1 |
ISSF requires 10 m ranges to be indoor (GTR 6.4.3.3 c) and puts 25 m and 50 m ranges indoors only exceptionally, for legal or climatic reasons (GTR 6.4.3.3 d).
What must the walls, ceiling and floor be lined with?
In Estonia the walls of an indoor range carry at least 1.2 cm of non-ricocheting material (Regulation No. 39, § 12(2)); in Germany the acoustic lining of walls and ceiling runs more than 2, 5 or 10 m from the firing line depending on the energy class (Schießstandrichtlinien 5.1.4.2).
RKIK Annex 2 describes the wall as sound insulation with timber boards or an equivalent on top, to catch a deflected bullet and reduce ricochet (points 35 and 38), and bans carpets and porous floor materials because they bind dust and powder residue (point 53). The German guideline asks for smooth, rebound-proof linings that take bullets arriving at 25–90° and for test certificates on the rebound protection of the materials used (5.1.4.2). The test method, the angles and the BulletTrap Baltic tile results are on how to stop ricochet in an indoor shooting range; baffles have their own page, shooting range baffles.
What bullet trap does an indoor range need?
Neither the Estonian nor the Latvian regulation gives a trap thickness: Estonia asks that the trap receives all bullets (No. 39, § 12(5)), Latvia that it matches the ammunition used (No. 494, 7.9).
The German guideline is more specific: a serial trap system is admitted only after a type test of at least 10,000 shots per trajectory, assessed by two independent range experts (2.8.4), and cleaning-wool and wooden-block traps are not allowed in indoor ranges (5.1.8). RKIK Annex 2 adds an acoustic point: the trap stands on its own foundation (127 c). How thick the steel behind a rubber trap should be, by document and by calibre, is on steel backing plate thickness; the trap itself is on bullet traps.
What ventilation, lighting and acoustics does an indoor range need?
RKIK Annex 2 asks for forced ventilation with exhaust 10 % above supply and at most 0.2 m/s of air speed at the firing position (points 66, 72, 81).
- Air: 4–6 air changes per hour at the firing line and 2 per hour for the hall as a whole (RKIK 84). Details on shooting range ventilation requirements and lead dust in an indoor range.
- Light: RKIK asks for at least 1,000 lx on a 25 m target, 2,000 lx at 50 m and 500 lx in the hall (points 108, 109). ISSF asks for at least 1,500 lx on targets at 10, 25 and 50 m (GTR 6.4.14). Poland asks for 300 lx in the hall and 1,000 lx on targets in police ranges (§ 26). The documents differ, so the one that applies to the project decides.
- Sound: RKIK sets a reverberation time of at most 1.0–1.5 s (128 a); the German guideline sets T60 below 0.5 s (5.1.10).
- Fire: no tracer ammunition in an indoor range because of the fire risk (RKIK 2 c). More on fire risk of rubber bullet traps.
Who approves an indoor range before the first shot?
In Germany a recognised range expert takes part in the check before first use, and a range where licensed firearms are used is re-checked every 4 years (WaffG § 27a(1)).
- Estonia: written consent of the local government and of the Police and Border Guard Board (Weapons Act, § 84(3)); the owner has the range checked at least once a year (Regulation No. 39, § 7).
- Latvia: for category 2 and 3 ranges the application goes to the municipality (No. 494, point 16).
- Germany: permit of the competent authority (WaffG § 27(1)); a recognised range expert gives a planning opinion on the design (Schießstandrichtlinien 1.3) and takes part in the acceptance (1.5).
- Poland, police ranges: an attestation based on control firing, an opinion of a scientific institution and air measurements by an accredited laboratory (§ 30); re-checks at least every 3 years (§ 34).
What does BulletTrap Baltic supply for an indoor range?
BulletTrap Baltic supplies the ballistic package of an indoor range, from the 200 mm block trap in zone I to the clearing barrels in zone III, and prepares the documentation for the tender file.
BulletTrap Baltic (MB Murakana, Vilnius) works either as a specialist subcontractor for ballistic protection under the builder’s main contract or as a consultant and tender partner directly to the contracting authority. The rubber lining was tested at the Royal Military Academy (Brussels), Department of Weapon Systems and Ballistics, an ISO 17025 laboratory (BELAC 273-TEST): 67 shots, 5 calibres, 10 m. Delivery is from Lithuania across the EU. How a range project runs is described on shooting range design, fit-out and tender support.
Questions about equipping an indoor range
What equipment does an indoor shooting range need in Europe?
Equipment for three zones: in the protection zone a bullet trap, the steel plate behind it and the back wall; in the intermediate zone bullet-resistant, non-ricocheting lining on walls, ceiling and floor plus baffles; in the safe zone the entrance and clearing area. Forced ventilation, target lighting and acoustic treatment cover the whole hall. The split follows RKIK Annex 2, point 26.
What is the minimum length of an indoor shooting range?
The shooting distance plus 5 m, according to RKIK Annex 2, point 18: the extra length holds the firing points and the bullet trap. A 25 m range therefore needs a hall of at least 30 m, measured from the farthest firing line.
How high must the ceiling of an indoor range be?
At least 2.20 m of clear height including baffles under RKIK Annex 2 (points 19 and 41), at least 2 m under Latvian Regulation No. 494 (point 7.6), and at least 3.3 m for Polish police ranges, 2.5 m in reconstructed buildings (Dz.U. 2022/848, § 8).
Can a 25 m or 50 m competition range be built indoors?
Only exceptionally. ISSF requires 10 m ranges to be indoor ranges (GTR 6.4.3.3 c) and allows 25 m and 50 m ranges indoors only for legal or climatic reasons (GTR 6.4.3.3 d).
How much light do the targets need?
RKIK Annex 2 asks for at least 1,000 lx on a 25 m target and 2,000 lx at 50 m (point 108). ISSF asks for at least 1,500 lx on the targets (GTR 6.4.14), and Polish police ranges for 1,000 lx (§ 26). Use the figure of the document that applies to the project.
Which ammunition is not allowed in an indoor range?
RKIK Annex 2 limits indoor ranges to weapons with a muzzle energy up to 4,500 J (point 2 a) and excludes tracer ammunition because of the fire risk (2 c) and black-powder ammunition (2 d).
Does BulletTrap Baltic supply the whole indoor range?
BulletTrap Baltic supplies the ballistic package: bullet traps, anti-ricochet tiles for walls, ceiling, baffles and floor, clearing barrels, targets and ballistic roller shutters. Ventilation, lighting and fire systems are specified by the project’s building-services designers; send BulletTrap Baltic the drawings so the trap and lining fit around them.
Which documents does BulletTrap Baltic provide for the range file?
Test reports by number and date (ES-230403 and ES-240131 from the Royal Military Academy, Brussels), CE marking and declaration of performance, the fire classification and the manufacturer’s quality certificate. The German guideline, for example, asks for test certificates on the rebound protection of lining materials (Schießstandrichtlinien 5.1.4.2).
