bamabound 0 Posted May 31, 2010 Report Share Posted May 31, 2010 (edited) I have been following everyone's advice and suggestions on getting the 12 to work with low brass. The only thing I did not do was drill the gas port holes bigger. But the thing that made it finally work was replacing the recoil spring. I bought the #1 and #2 from CSS, not knowing which would work. They both work and it will almost eject low brass on the #1 setting on the gas plug. So, if you are having trouble with low brass not cycling, a easy fix might be to replace the recoil spring Edited May 31, 2010 by bamabound Quote Link to post Share on other sites
geepelton 105 Posted May 31, 2010 Report Share Posted May 31, 2010 I also changed to a #1 spring and it did make a big difference. I since went on to open thee gas ports, twister puck, polished the bolt carrier and gunfixers plug. It cycles like a dream now... Quote Link to post Share on other sites
mscottrogers 56 Posted May 31, 2010 Report Share Posted May 31, 2010 I don't recommend getting your s 12 to cycle close on 1, it will beat the hell out of your gun. Quote Link to post Share on other sites
Cobra 76 two 2,677 Posted May 31, 2010 Report Share Posted May 31, 2010 Be careful with a low powered recoil spring if you decide to shoot some slugs or other magnum loads. I know someone who got a nick in their forehead from doing that and the dust cover having flown off and smacked him. If you can't turn the gas down enough using the plug, you should keep the original front spring handy to swap out whenever using higher powered loads. Quote Link to post Share on other sites

I will change springs when shooting high brass or slugs. I am just overjoyed to have it cycle with low brass. My shoulder is pleased too! Quote Link to post Share on other sites
