ViciousOutlaw 0 Posted January 1, 2012 Report Share Posted January 1, 2012 Alright folks, I am currently converting a 5.45. I have the rear done and am now working on the FSB and gas block switch. I have cut the old ones off and now need to put the two from the parts kit on. The problem is I cannot get the FSB and gas block off of the cut barrel parts from the parts kit. The pins will NOT budge. I have tried covering them in liquid wrench and tapping them out with a hammer to no avail. As well as trying to press them off with a 12 ton press. The problem with the press is whatever I use to try to press the pins out with, ends up flying off without pushing the pins at all. What am I doing wrong? Thanks!

Lone Eagle 839 Posted January 1, 2012 Report Share Posted January 1, 2012 Sounds like you have one of the newer FSB/gas blocks that are dimpled instead of pinned. A picture would be of great assistance here. Quote Link to post Share on other sites
ViciousOutlaw 0 Posted January 1, 2012 Author Report Share Posted January 1, 2012 I cut the old fsb and gas block from the saiga barrel. I am having problems removing the fsb and gas block from the cut barrel that came in my parts kit. Here is what I am talking about. Quote Link to post Share on other sites
CnRnut 3 Posted January 3, 2012 Report Share Posted January 3, 2012 Get yourself a chunk of hardwood and a grinder with a sander disc,and cut the profile of the GB and FSB into the wood. When driving the pins out,it's all about supporting the GB/FSB. Then you can drive the pins with a nail set and hammer to start then and a puch once they start to move. I've driven many pins with a block of oak as a support with holes for the pins to slide into. Quote Link to post Share on other sites
jamesavery22 54 Posted January 3, 2012 Report Share Posted January 3, 2012 Well a press with a captive pin holder(Like this:http://ak-builder.com/index.php?dispatch=products.view&product_id=29978) would be ideal. I don't know of a pin holder that is made for a hardened 3mm pin though... You could turn down a larger pin. I've never seen a 3mm GB or FSB pin I couldn't drift out with some punches and a hammer. I've definitely had pins that were too large for the hole that I couldn't hammer in. None I couldn't hammer out though. What are you using as a punch? You could do CnRnut's advice on fabricating a hardwood support. I'd just chuck up the barrel in the vice since thats a cut off anyway. Who cares if you mar up the cut barrel piece.

CnRnut 3 Posted January 4, 2012 Report Share Posted January 4, 2012 I'd just chuck up the barrel in the vice since thats a cut off anyway. Who cares if you mar up the cut barrel piece. I've used a vice as well on stubs,but the wood block works great when working on full barrels. Quote Link to post Share on other sites
markdavidson 28 Posted January 4, 2012 Report Share Posted January 4, 2012 silly question, but the ends (or one end) of the pins aren't tac-welded in place are they? Quote Link to post Share on other sites
GregM1 241 Posted January 4, 2012 Report Share Posted January 4, 2012 have you tried pushing the pins from both sides? sometimes there is only one way for them to move. Quote Link to post Share on other sites

mancat 2,368 Posted January 5, 2012 Report Share Posted January 5, 2012 (edited) The Bulgarian FSB/GSB pins are often peened on one side, but the finish makes it a bit hard to tell. Make sure you're punching them out from the correct side, which should be noticeably smaller. Edited January 5, 2012 by mancat Quote Link to post Share on other sites
