Complete 5.56mm upper receiver with pinned/welded suppressor, 11.5" barrel, M-LOK handguard, and low-profile gas block. Single tax stamp required. 134 dB rated.
The Turbo K-RB represents a thoughtful approach to suppressed rifle design. By integrating the suppressor directly to the barrel and pinning and welding the assembly, you achieve a combined barrel and suppressor length of just over 16 inches—allowing you to build a compact, controllable rifle while requiring only a single tax stamp purchase.
Note: Does not include bolt carrier assembly or charging handle.
The low-profile suppressor gas block is engineered to reduce blowback and moderate cyclic rates, resulting in a more controllable shooting experience. The M-LOK handguard provides modern mounting flexibility for accessories without unnecessary bulk. This upper receiver group delivers genuine suppression performance in a package that doesn't compromise on practicality or reliability.
