SilencerCo Delta Stormproof 1/2"-28 Thread Protector 22 LR

The SilencerCo Delta Stormproof is a black oxide stainless steel thread protector for 22 LR rimfire barrels threaded 1/2"-28. It covers and protects the threads of a barrel when no muzzle device or suppressor is attached.

The thread protector is machined to the 28 threads-per-inch pitch of a 1/2"-28 barrel and finished in black oxide for a black, matching appearance. Its stainless steel construction is intended to hold up to repeated installation and removal.

It can serve as a replacement for a previously purchased adapter. Where a gunsmith threads a barrel with SilencerCo's O-ring engagement feature, this thread protector is noted as a suitable fit.
