MyGrassIsBlue05 14 Posted April 21, 2012 Report Share Posted April 21, 2012 I posted this in the tech section, but after seeing no replies maybe it'll get some more attention over here. I was cleaning my IZ340, and noticed the small pin in the front sight block, responsible for retaining the muzzle brake detent and spring was loose, and easily slide in and out rather easily. Should this be loose? Is something holding it in, or do I need to fix it? Many thanks MGIB Quote Link to post Share on other sites
wtjosaas 72 Posted April 21, 2012 Report Share Posted April 21, 2012 I have the same thing on mine. Afraid it might fall out and get lost. Quote Link to post Share on other sites
thebuns1 4,323 Posted April 21, 2012 Report Share Posted April 21, 2012 (edited) it wont fall out so long as you leave it be. it will move a bit one way or the other fairly easy. but the last one i took out i needed a punch for the full removal.

Red Star 38 Posted April 23, 2012 Report Share Posted April 23, 2012 so this hole that the retaining pin is in goes all the way through the front sight block, and there is nothing to keep this pin from backing out?? Quote Link to post Share on other sites
thebuns1 4,323 Posted April 25, 2012 Report Share Posted April 25, 2012 the detent pin spring should aid in keeping the pin from falling out. a little play is normal. i wouldnt worry about it so long as its not falling out on its own. of course if your worried about it, then you could opt to replace it. or just mash it a little on the side that has the hollowed out portion of the pin.

MyGrassIsBlue05 14 Posted April 27, 2012 Author Report Share Posted April 27, 2012 Thanks for the replies. I'll keep an eye on it and see how it does. Quote Link to post Share on other sites
Shankspony 40 Posted May 29, 2012 Report Share Posted May 29, 2012 (edited) I lost mine this weekend... the plunger "spring detent pin" and spring are gone, leaving me with only the plunger (brake detent pin). Other FSBs seem to use a two-piece detent rather than this three-piece. Edited May 29, 2012 by Shankspony Quote Link to post Share on other sites

(at least on russian ones). i mushroomed the side of mine to help it stay in better with a punch. Quote Link to post Share on other sites
