2018年3月12日 · The Benelli M4 is physically a better built gun, I have simply never held a better built shotgun than a Benelli M4. With that said the 1301 is a very well built, very well assembled gun and I can't find anyplace that they left anything lose or not centered properly.

It seems rather odd that the M4 carbine needs to have a larger extreme spread to meet the mil-spec when firing the load that supposedly has “match-like” accuracy.
