I am asking which pins. My pins are different than the pics you directed me too. I just want to know what pins get removed simply. Quote Link to post Share on other sites

I am asking which pins. My pins are different than the pics you directed me too. I just want to know what pins get removed simply. Sorry, try this thread: http://forum.saiga-1...-block-removal/ from the looks of the picture, I would just remove the two bottom pins as they look to be holding the gas block to the barrel. The other #1 pin looks to be only for the gas adjustment pin Edited February 21, 2012 by AZG Quote Link to post Share on other sites
Mullet Man 2,114 Posted February 21, 2012 Report Share Posted February 21, 2012 If it looks like "pin #1" in your pic, goes into the barrel (hard to tell from the pic), then remove it. It might be a good idea just to remove all 3 and be done with it, if you're not sure about it. Just keep track of which pin goes where, just in case. Dont forget there is a spring behind pin#1, dont lose it. 1 Quote Link to post Share on other sites
1liter 20 Posted February 21, 2012 Report Share Posted February 21, 2012 AZG is correct the two lower pins hold the block on. The upper pin holds your retaining pin and spring for adjustment of your gas system. Quote Link to post Share on other sites
Dozer 4 Posted February 22, 2012 Author Report Share Posted February 22, 2012 So I started my attempts to remove the pins from my gas block seem in the picture higher in the post. Pin 3 came right out using a good size hammer and a pin punch. Pin 2 aboslutely refused to budge no matter how hard I hit on it. I even attempted to heat the pin up. Has anyone removed the gas block from a S20? Do both these pins need to be removed in order to get the gas block off? I am 2/3 rds the way through my conversion and I need to get the most important part completed and the one pin wont budge. PLEASE HELP... Can I drill the pin out? I work in a plant where I have access to a complete machine shop where I can manufacture another pin if needed. My bigger question is do both the bottom pins need to be removed? And has anyoner had to drill out the pin in order to get one out? I need access to the gas ports to open them up...and complete the D-mod Quote Link to post Share on other sites
1liter 20 Posted February 22, 2012 Report Share Posted February 22, 2012 Are you having cycling problems? Pin's 2 and 3 need to be removed. Use a BFH and hit it hard, I suppose you could use a drill press as a last resort. Never done it. Quote Link to post Share on other sites
Mullet Man 2,114 Posted February 22, 2012 Report Share Posted February 22, 2012 If you work in a plant with access to tools, there has to be a shop press around somewhere. You can also use the drill press as a shop press of sorts Quote Link to post Share on other sites
magsite20 1,664 Posted February 22, 2012 Report Share Posted February 22, 2012 Shorten a punch, use vice grips to hold it, and use a really BFH, that’s what I had to do to get the pins out of mine. Both on mine were TIGHT. Quote Link to post Share on other sites
Dozer 4 Posted February 22, 2012 Author Report Share Posted February 22, 2012 Ok so I brought into my (" zero tolerance on guns in the workplace") workplace and put the pins in a 25 tom hydraulic press and the pins came out. Them we used a BFH woth a piece of 80/20 aluminum strut and beat the Gas Block off. No issues came off fairly easy. Then with the gas tube off we put the barrel on a bridgeport end mill and drilled out the three holes to 3/32 and added a fourth hole. We also angled the holes towards the reciever at a 40 degree angle. I took the gas block and opened the hole where the now newly enlarged 4 holes come into the gas block and enlarged that so all four holes hare not blocked by the gas block. When we reassembled the gas block we used 80/20 aluminum strut and a BFH and the gas block slid right on, no issues. So when you look inside the gas block now all four gas ports are clearly visible. I also polished all angels,slide and hammer for smoother action. I also order a low brass reliablity kit from CSS should arrive in a day. Cant wait to get to wally world and buy so cheap rounds to test. I will add this to a new post if nayone else can get some use from it. Quote Link to post Share on other sites
