ProtoBarrel Mod Dedicated 22LR 5.5 - Thread Adapter

Terrapin Tactical 4.3MiB Released December 26, 2025, 2:15 AM

Modified the AWCY? ProtoBarrel to be able to be made into a 5.5 inch barrel to keep our plastics nice and cool. There are options available to use the outer carbon fiber tube or not. This is the insertable thread adapter muzzle device, the best option for longevity.
