Bar 10 problem

[Fridge Gnome]

Teflon is off the o-ring, I lubed it, but it is still leaking, I was reading a forum on airsoft retreat where a guy was having the same problem, where it sounded like it was coming from the middle of the cylinder, they suggested a new o-ring, so I getting a #13 and #14 o-ring

uuh. ok so i recently bought a laylax spring guide, laylax 150, red piston, and nine ball hopup bucking, and a laylax reinforced sear.

I put it all together and its slam firing! I can find nothing broken with it, the only problem is that one screw that holds the trigger system to the reciever will not stay in.

what could be wrong, last time it slam fired I just opened it up and coulding find anything wrong, put it back together and it worked fine.

HALP!

I've seen this with a Maruzen before. Try switching to the old spring guide and see if it's still slam firing.

If that solves your problem, then this is your problem: the "base" of the spring guide is too thick, and is not allowing the sears to engage properly. Quite frankly, I'm not sure how to (properly) fix that without a machine shop (and if you're going that route, you might as well make your own.

If you do end up replacing it, I suggest Polarstar.

I will try the old spring guide, and find a longer screw.
