Angstadt Arms SB mod 39MM Coin Barrel Glock Compatible
DESIGNED FOR THE SHOOTER
An advanced bolt hold open and flared magwell allow for faster reloads while the integrated oversized trigger guard allows for the use of gloves when shooting.
DEDICATED UPPER RECEIVER
The matching lightweight slick side upper receiver features an ejection port appropriately sized for pistol casings.
To maximize training efficiency, the lower receiver utilizes standard AR-15 controls and features only a handful of proprietary parts, ensuring compatibility with most all aftermarket AR-15 Mil-Spec components.
Our lower receivers can be configured to accept GLOCK® magazines in 9mm, .40 S&W, .357 SIG and 45 ACP.
LIGHTER AND STRONGER
The 0940 and 1045 receivers are crafted from 7075-T6 aerospace billet aluminum to be lighter and stronger.
