Armaspec Fixed Stock to Carbine Spacer A1/A2 for SRS/SMB

The Armaspec Fixed Stock to Carbine Spacer is a dedicated 2.75 in spacer designed to adapt A1 and A2 style fixed stocks for use with the Armaspec Stealth Recoil Spring (SRS) or Sound Mitigation Buffer (SMB) systems. Machined by Armaspec in the USA, this simple drop-in spacer lets builders run a classic A1 or A2 buttstock configuration on an AR-15 lower while still taking advantage of the recoil reduction and sound mitigation performance of the SRS or SMB buffer/spring assembly.

The spacer installs between the receiver extension and the fixed stock, correctly spacing the stock to clear the shorter overall length of the SRS or SMB unit. At just 1.5 oz, it adds negligible weight to the build while restoring the proper stock-to-receiver relationship. Finished in a durable black coating to match standard AR-15 componentry, the ARM154-RFL is a straightforward solution for shooters wanting to pair a traditional fixed A1/A2 stock with Armaspec's modern recoil and sound management systems.
