Full Length Benelli M4 Carbon Fiber Magazine

The Briley M4 Carbon Fiber Magazine replaces the factory 5+1 round magazine on Benelli M4 and M1014 Shotguns to 7+1.

Design and Construction: The Briley M4 Carbon Fiber Magazine is made from twill weave carbon fiber with 17-4 stainless end caps, which offers a lightweight and durable alternative to traditional metal magazine tubes. The carbon fiber construction provides strength and rigidity while reducing overall weight.

Easy Installation: The Briley M4 Carbon Replacement is designed for straightforward installation. Fitting will require the removal of the original magazine. Magazines are screwed into the receiver using a thread locker which will require heat to break down. This should be done by an experienced gunsmith to avoid damage to both parts and finish.

Compatibility: The Briley M4 Carbon Replacement is specifically designed to fit the Benelli M4 shotgun. "Clone" M4s produced by other manufacturers may be compatible, but fit on these models is not guaranteed.

Benefits: The construction of the Briley M4 Carbon Fiber Magazine offers several benefits. It reduces the overall weight of the shotgun, which can be advantageous for shooters looking to minimize fatigue during extended shooting sessions and for those seeking a more balanced firearm. Additionally, carbon fiber is resistant to corrosion, making it suitable for use in various environmental conditions.

Additionally, a longer spring is not required as the factory spring will still ensure reliable function. The magazine is supplied with a stainless steel follower that is thinner on the face to allow for more room in the magazine. Insertion of the last cartridge in the magazine can require a little more pressure, but the clearance ahead of the latch is adequate and the shotgun will function reliably.

PLEASE NOTE: The magazine must be securely held in the receiver with 271 Loctite or equivalent thread locking compound. The magazine retains the barrel into the gun; if the magazine backs out of the gun under firing it will cause malfunctions and damage to the receiver.
