dunno man i had the 11 inch pistol and shot maybe 3k thru it without a hickup i also own the 556 model rifle and neither have given a single issue as for swaping the caliber ive heard its quick
as for accuracy mine was accurate as hell so not sure sounds like a shooter issue
and plenty of folks shoot it suppressed
