The BOSS .30 Caliber Standard End Cap for 1.5-Inch Housing in black (brand part no. EC-150-762-SS-SE-BLK) is a replacement end cap for B.O.S.S. silencer models built on the 1.5-inch tube, sized for .30 caliber (7.62mm) use. It is the standard, non-vented configuration that B.O.S.S. lists for non-gas-blowback actions such as bolt guns and piston rifles. The maker finishes it in black nitride only and lists the weight at 1.4 ounces. It is the end cap only, so you still need a B.O.S.S. suppressor with a 1.5-inch tube. Choose it as a spare or as a replacement when reconfiguring a .30 caliber can for a bolt gun.

Frequently Asked Questions

Which actions is the standard .30 caliber cap meant for? B.O.S.S. lists the standard cap for non-gas-blowback actions such as bolt guns and piston rifles. Gas blowback actions such as a traditional AR-15 are matched to the vented cap, which the maker recommends for gas impingement firearms to reduce back pressure and gas exposure.

Does it fit other B.O.S.S. housing sizes? No. B.O.S.S. says this end cap only fits its 1.5-inch tubes.

Does it come with a suppressor? No. It is the replacement end cap only.
