SRU Precision Bullpup Conversion Kits for AR-15 and Ruger 10/22

SRU Precision designs and builds bullpup conversion chassis in Taiwan. The SARB-15 turns your AR-15 into a compact bullpup that keeps your barrel length, and the SRUNA-22 does the same for the Ruger 10/22. Both kits come in real-steel and airsoft versions, made from injection-molded PA66 with carbon fiber and CNC-machined 6061-T6 aluminum, with a future-tech look you will not find anywhere else. Kits are not firearms and are not serialized parts. We ship worldwide from Taiwan.
