Comstock Armory Low Profile Rearden/Plan-B Titanium Recessed Suppressor Adapter - RPA-B-TI

Comstock Armory Low Profile Rearden/Plan-B Titanium Recessed Suppressor Adapter

The Comstock Armory Titanium Recessed Plan-B Adapter is designed for suppressors using the standard HUB/Bravo 1.375-24 interface. Its recessed profile seats compatible Plan-B muzzle devices deeper into the suppressor, helping reduce overall system length and create a tighter handguard-to-suppressor gap. At just 1.2 ounces, it provides an exceptionally lightweight mounting solution without sacrificing strength.

Machined from Grade 5 titanium and finished with a durable PVD coating, the adapter is compatible with Comstock, Rearden, and other common Plan-B muzzle devices. Compared with Comstock’s standard LPA, the RPA positions the muzzle device 0.40 inches deeper into the suppressor.
