Having serviced and repaired the full range of tactical shotguns I agree with JT111 they are excellent and reliable guns. The M4 is a bit more complicated to maintain and sensitive to certain loads and a lot more expensive, the M2 is great all round gun, the only part that ever required replacing was the inertia spring, the inspection standard was very tight for length, from memory the length, new, should be 2.7cm, the minimum was 2.67cm. this was after many thousands of rounds. I will confirm the spring specs and post confirmation later
