so Im thinking about SBRing one of my Mini's. For those who have one or have shot one, is the muzzle blast/concussion the same as or similar to that of a 10-13" AR? Im assuming it is but just wanting conformation from someone that actually has one .
No, not even close. It is an 8.5" barrel in 9mm. Muzzle blast is minimal.
Huh? I think the OP was thinking about SBRing a Mini-14 chambered in 5.56 NATO.
Judging from my buddy's regular Mini-14 with an obnoxiously loud and bright muzzle blast/flash (no flash suppressor), especially at an indoor range, I can only imagine what a bare 10" to 13"-barreled Mini-14 would be like.
I hope you're planning on threading it for a flash suppressor.
