      Fits Mossberg 940 Pro SPX

      Posted by Unknown on 6th Oct 2025

      There is a swell in the barrel at the muzzle that forces you to mount the clamp a little closer to the bayo lug than pictured, but it works and takes a bayonet as advertised. 5 round capacity now with 2 3/4" shells.

      Customer service and extension tube

      Posted by Erik Gillespie on 31st Mar 2025

      I had some questions about their products, and their kits, so I called and the customer service was great. Once I got the kit, which at first I thought was over priced, I was pleasantly surprised. Well machined and solid, the extension tube is solid, and the extension brace is comparable to the MT product. The sim of the parts are worth the kit price, great fit and finish. I would recommend if you are looking to outfit your shotgun with a bayonet.

      Everything I expected.

      Perhapse a more snug fit around the barrel ext.dia. re: actual bayonet lug clamp. Also, perhaps a more robust forward barrel clamp, you have one in stock I believe would work wonderfully.
