I finally have my Benelli M4 setup the way I like it (to replace the Beretta 1301 Tac as my primary house long gun).
Benelli M4 18.5"
Mesa Tactical Urbino stock w/Limbsaver buttpad
Freedom Fighter Tactical titanium full length magazine tube (7+1+1 ghost)
Freedom Fighter Tactical 1/2" titanium charging handle
XS Big Dot tritium front sight
assorted 922r parts because I'm a law abiding subject
Patterns Federal LE13300 #00 buck into 8" at 30 yards.
At 12 yards on a full size IPSC steel silhouette I was getting 5 shots on steel from low ready in 1.3 seconds (.20 splits) with #00.
So far it's fed every slug, buck and birdshot (around 350 rounds so far most of it #00) I've run through it with nary a hiccup, and best of all no tube lock from bumping the bolt release.
