What’s Included
- Hammerli Arms TAC R1 22 C .22 LR rifle
Built on the AR-15 platform, this TAC R1 22 C uses aluminum upper and lower receivers with a matte black/gray finish. It was made in Germany by Umarex and carries DE proof marks, along with the U.S. distributor marking "HAMMERLI ARMS FT. SMITH, AR."
The 16.1 in barrel is threaded 1/2x28 UNEF and paired with a semi-automatic blowback action. The upper includes a brass deflector and dust cover, and it is configured without a forward assist. A manual-documented bolt-speed adjustment feature allows tuning of the cycling speed for this rimfire system.
A free-float 13 in aluminum M-LOK handguard with integrated QD sling sockets runs in line with a continuous 12-o'clock Picatinny rail bridging the receiver and handguard. Sighting is handled by flip-up sights: a dual-aperture rear and an elevation-adjustable front, delivering a sight radius of 20.1 in.
The rifle uses a rear charging handle, a right-side magazine release, and a manual safety selector. Furniture includes a 5-position telescoping polymer stock with an approximate length-of-pull range of 12.0–15.5 in and an AR-style pistol grip marked "HAMMERLI." Overall length is approximately 32.7–35.8 in, and weight is about 6.5 lb.
