So... I'm getting my gf3 back from psa soon, and I was contemplating doing some front end work by a gunsmith. Frontsight gasblock combo, barrel chop/pin weld. My only concern is what gasblock to use since I think psa puts thier a smidge hearing than combloc?

I ran an ultimak for awhile and the only way I could get the bolts to torque was to use. 0012" shimming stock (per ultimak, didn't come up with that solution on my own). So do you think that a new gasblock would work fine with the rear sight block? Or would I most likely end up having issues?


P. S. AK dudes on this forum have been very helpful as I learn this platform. Thanks guys.

I like the JMAC GBC-13

Thanks dude! Is it for 45 or 90 degree ports?

Thanks dude! I just found one on in stock too.

It is 90 but can work on 45. I have actual used them on a few in more than one way. I milled out a slot to line up and it worked very well. They are built like tanks and will take some abuse.

I went with the adjustable one from definitive arms. Unlike the jmac one, it locks at each numbered setting.  I use 7 for 196gr subs, 5 for 154gr, 3 for 122gr.
