Benelli m4 - Briley Benelli M4 12ga 8 Round Shotgun Magazine

I don’t think people understand how this tube works or fits, I will say that it’s perfect and looks awesome. You can actually feel the weight difference in your gun, for the M4 the factory spring works perfectly fine in a non restricted tube, benelli sends each gun from the factory with a seven round spring, be sure to use the follower that comes with the briley 3 gun tube to make sure your tube is functioning properly. I don’t regret the purchase.
