AK Railed Gas Tube
Installed this on a PSA GF3 AK. Took about ten minutes to disassemble the rifle, install and reassemble. The rear of the gas tube rests tight in the rear sight block and I had to tap the tube in during installation but this aids in stopping movement once you install a red dot sight. Pleased with my purchase.
I should have bought 2 more!
I bought this a couple years ago when it was in sale and there was the additional 10% off if you spent $100 or more. I have this on a PSAK 47. Mounted on it is a Bushnell Ak47 red dot also from Brownell from the same sale. I Have put about 600 rounds and everything is still on nice and tight and holds zero. I did put blue loctite on all the screws, that was 2 years ago. The gas tube was easy to install, solid construction, nice finish. I prefer this to mount an optic over the side rail mount because you save space and can remove the upper receiver plate easier I will wait for another sale and buy 2 more.
So far so good
According to the installation instructions you are supposed to tighten the front nut hand tight before torquing down the set screws. When I did it that way, the gas tube started to become noticeably loose after 20 rds. So I reinstalled and this time used a wrench on the front nut, not crazy tight though, and I'm having much better luck. Staying in place and holding zero after 100 rds, and able to repeatedly hit a steel target at 130 yd with a trs25 red dot.
