vintagedude88 16 Posted May 10, 2009 Report Share Posted May 10, 2009 Does anyone know an easy way to remove the FSB on the S308? I tried using a small punch to pound out the pins but it wouldn't go. I'm punching it from the left side. I seems like thats the small end of the pins rather than the right side. Am I wrong? Haven't tried punching it from the right side yet. I'm afraid of hurting the barrel if I wack it too hard. Any help would be appreciated. If you're wondering, I'm removing the FSB to put on a muzzle brake. Thanks.

Deussne 38 Posted May 10, 2009 Report Share Posted May 10, 2009 Whack it harder. Yes most pins seem to go in only one way. As you mentioned you see the one with a smaller diameter side thats the side to push from. If anything get a torch and try heating the fsb and cooling the barrel at the same time by having some ice on it. It usually works for me when i get a stubborn part. Now if you have a pneumatic press thats a different story. Quote Link to post Share on other sites
KrisFox 69 Posted May 10, 2009 Report Share Posted May 10, 2009 Before I go the torch rout I will soak it in penitraiting oil. If I have a press I can press the pin out. You can press it out using a vice but you'll need to build a jig. Quote Link to post Share on other sites
Bayoupiper 738 Posted May 10, 2009 Report Share Posted May 10, 2009 (edited) The pins WILL come out without resorting to a torch. Just keep at it. Now the FSB itself my be a little tight. On mine, it just took a couple of taps froma wooden mallet on the rear of the block and it slid right off. Edited May 10, 2009 by Will Quote Link to post Share on other sites
srajadnya 0 Posted May 10, 2009 Report Share Posted May 10, 2009 I plan to do exactly the same. Being from NJ, I can't have a threaded brake, it needs to be welded. I have done some welding in the past but never on a gun barrel. What's the recommended welding method? Alternatively, I will have to locate a gunsmith. Which muzzle brake is good that's weld-on type? I like the look of the Tantal brake, but that comes in threaded ... Quote Link to post Share on other sites
vintagedude88 16 Posted May 11, 2009 Author Report Share Posted May 11, 2009 I gave up on trying to push the pins out so I drilled them out. Now that I have it out, I've wacked at the FSB several times and it wouldn't budge. I hate to bring out a torch. Anyone have any ideas on how to get the FSB knocked off? Could I cut it off? Please help. Thanks. Quote Link to post Share on other sites

Please help. Thanks. I think Cobra suggested that you cut-off on the bottom portion of the FSB. Use a Dremel or equivalent cut-off wheel and cut the FSB off without cutting through the barrel (!). Then pry using a cold-chisel and open-up that sucker, then knock-off using a non-marring instrument (wood-block + hammer) against FSB back to front. I haven't tried this, so don't know how this will work. YMMV. Good luck. Quote Link to post Share on other sites

I haven't tried this, so don't know how this will work. YMMV. Good luck. Okay, I did it. I took a cut-off wheel to the FSB and cut along the bottom on the centerline. I tried to cut as little as possible. Once I got far enough, I wedged a flat head screw driver in the cut to pry it open. It wiggled a bit but still wouldn't budge forward. I pryed it again and it wiggled some more. After that, I took a rubber mallet and strucked it once and it finally came off. Once off, I noticed I had cut a bit into the barrel about .050" into it. I hope it won't hurt the barrel's integrity. I figure since the pin hole on top were grooved at almost .060", my cut should be no less a problem to the barrel than the pin grooves. Besides, wouldn't the threads on the barrel be about .060" or more deep on the barrel? Now that the FSB is out, I now have to worry about cutting the threads without breaking the alignment tool or the die. Thanks to everyone for the help. Quote Link to post Share on other sites
