The Midwest Industries Pistol Buffer Tube is a great option when building an AR Pistol. This Pistol Buffer Tube features a shoulder for the SBM4 Arm Brace to rest against in order to increase the length of pull and it uses a standard end plate and castle nut which provides several rear sling mounting options.

The Midwest Industries Pistol Buffer Tube is long enough that the rear of the tube sits flush with the rear of the Sig Sauer SBM4. This completely fills the void at the rear of the SBM4 to provide more rigidity and it is long enough to bring an AR pistol with a 10.5" barrel to 26" overall length so you can install a vertical grip.

Kit Includes:

Buffer Tube Only. Buffer Spring and Buffer sold separately.
