SIG SAUER now offers a line of its direct impingement SIGM400carbines and pistols with B5 Systems components.

Starting with the SIGM400 carbine, the SIG SAUER improved take on the direct impingement AR-style rifle, a B5 Systems SOPMOD 6-position telescoping stock, pistol grip, and KEYMOD carbine handguards are added in gray or foliage. The SIGM400 B5 Pistol also sports the B5 grip and KEYMOD handguards, all in Flat Dark Earth (FDE).

“We are excited to partner with B5 Systems. They offer high quality, ‘operator-grade’ components,” said Jarrod McDevitt, SIG SAUER Rifle Product Manager.

Featuring 1:7 twist with chrome-lined bores and chambers, the SIGM400 B5 carbines and pistols are machined from 7075-T6 aircraft grade aluminum and are finished in hard coat anodize finish. Both come with SIG SAUER locking flip-up rear sights and have M1913 Picatinny flat-top upper receivers.
