Colt’s Manufacturing Carbine MPS-B 5.56 NATO Semi-Auto Rifle

Product Description

The Colt’s Manufacturing Carbine MPS-B is a semi-auto rifle chambered in 5.56 NATO with a 16.1″ chrome-lined barrel. It holds 30+1 rounds and has a manual safety. Overall length is 32″, and the finish is matte black anodized.

What sets this carbine apart is the Magpul furniture. It has a Magpul MOE telescoping stock, so you can adjust length of pull to fit your frame or your gear. A Magpul M-LOK vertical grip comes as part of the setup. Sights are an adjustable post with Magpul MBUS Gen 2, so you have iron sights ready to use.

Barrel and muzzle

The barrel has a 1:7″ twist rate. It is threaded and carries a bird cage flash hider on the muzzle. The chrome-lined bore is a good fit for high round counts at the range.

This rifle suits shooters who want a Colt AR carbine for training, practice, or general-purpose use. It also works for anyone who wants a solid base to build on. Good pairings include a red dot or magnified optic, a quality sling, extra 30-round AR-style magazines, a weapon light, and a padded rifle case. Pick gear that matches how you plan to shoot.
