PROTEUS RIFLE 15
In creating the PR-15 project we collaborated with different EU-based companies, the goal of which is becoming the go-to AR-15 type rifle for shooters and professionals throughout Europe. The first and main iteration of this system is an all-purpose 12.5″ carbine offered as a built up “ready-to-go” weapon and training system (Mod. 1 — Full build list below), which enables us to bring you quality hardware at a seriously competitive price.
The base rifle is manufactured in Slovenia by Tinck Arms, featuring Magpul furniture and a custom Proteus RESGRU 11.5″ MLOK handguard utilizing the Tinck Arms clamping system. The package includes Silent Steel’s Compact Streamer flow-through suppressor and QD Muzzle Brake. Optics-wise we’ve partnered up with Optics Trade, who supply the Aimpont H2 Micro Reflex Sight which is mounted to the York Development Strutted Optic mount allowing for a more stand-up shooting posture improving situational awareness and ergonomics.
THE BUILD LIST (Mod. 1)
- Tinck Arms .223 REM 12.5″ MILSPEC Carbine
- Proteus Research 11.5″ Handguard (MLOK)
- Tinck Arms Tiger LT Charging Handle
- Magpul CTR Stock
- Magpul MOE-K Pistol Grip
- Silent Steel QD Muzzle Brake
- Silent Steel Compact Streamer
- York Development Strutted Optic Mount (Compatible with Flip Down magnifier mount and rail extension)
- Aimpoint H2 Micro Reflex Sight (provided by Optics Trade)

This build has been carefully developed and thought-through as the most optimal all-round usable and capable setup, with good parts availability, servicability and price-to-performance ratio. There have been no compromises made on quality of components and we believe the AR-15/PR-15 system is still on the cutting edge of adaptability, parts compatibility and ergonomics.
