Description
Extended/XL suppressor adapter compatible with Comstock, Rearden, and other common Plan-B muzzle devices. Currently the lightest extended steel Plan-B HUB adapter on the market at just 1.9 ounces. Compared to the standard LPA, the HPA gives an additional 0.4 of space in the blast chamber to fit longer muzzle devices. The rear cylindrical section is 1.08 wide and will tuck under nearly all handguards.
