SilencerCo AC3 Delta Adapter 1/2x28 22 LR

The SilencerCo Delta Adapter is a steel O-ring engagement barrel extension designed for use with 1/2x28 threaded 22 LR suppressors. It threads 1/2x28 male to 1/2x28 female, extending the barrel by 0.75 in while shortening 0.6 in of existing 1/2x28 threads down to 0.4 in for proper suppressor fit.

Compatible with SilencerCo Delta-series 22 LR suppressors including the Switchback 22, Sparrow 22, Spectre 22, Warlock 22, and Osprey Micro 22, this adapter is a popular choice for AR-15 22 LR conversion setups. A thread protector is included for safe handling and storage when the adapter is not in use.
