As the title of the thread states, I am considering the conversion of my M4 to a SBS (legally, of course). I was told by my gunsmith that there is a possibility of failure to cycle due to the shortened length of the barrel unless full house loads are used (i.e. 00 buck, slugs).
I know that Benelli makes a breaching version of this weapon, however I do not know if there is any physical difference between the M4 with 18.5" barrel versus the 14" breaching version other than the obviously shorter barrel length.
Anybody out there with experience on this? Any help would be greatly appreciated!
