Broken Benelli SBE II with photos... help please? in Benelli Posted January 24, 2013 Yes it is a stamped out part and they rarely break. Seen thousands of Benellis through my hands and the factory one for the SBE and M4 are different lengths, just different finish. That is why you'll have to have one for an SBE/SBEII (same thing) 3.5" shell. The 3" guns use shorter ones. Yes it is very simple, roll pin out, roll pin in and watch your spring placement. 3/32" punch if you need to know. Actually most roll pins break from wear (about 4000 to 7000 rounds) before the latch ever gives any. Seen some break if the trigger assembly was put in incorrectly and people try to "hammer" the bolt release closed.
