The angel custom springs aren't as bad as they are made out to be. I have a angel custom m190 and have put about 500 rounds through it and it still shoots at a nice 620 FPS measured with a DIY chronograph, although the first 15-20 shoot WAY hot. Like 800+ fps hot. Yes the spring compressed a lot (like three inches) to the point where it is neutral when un-cocked, but that makes the cylinder head go on easy, and the spring won't degrade just sitting.I haven't heard any good things about the angel custom springs, however I see no problems with the spring guide given if everything is the right dimension and the center rod doesn't unscrew with some lock-tite.
The spring may just be giving uneven pressure which doesn't allow the spring guide to sit evenly.
I assume you're using a stock trigger with upgraded sears?
Mine hasn't yet. Its an angel customs.Yes, I am using the stock trigger with upgraded sears.
So, I guess I'll go with laylax for a new spring, but do you guys know of any spring guides that don't screw off at all (preferably with bearings)?
