A&K M1873R M-LOK Lever Action Airsoft Gas Rifle (Model: Medium / Black)

"There was extra orings added into this and they actually do make the seal better. This is also the best version to get if you intend to hpa tap it. The front end screws directly into the gas port and a&k being wise beyond There years threaded this to the standard hpa fittings that are on the side of most regs that use qd 6mm lines like man craft. All versions of this use proprietary barrels that have a smaller outter diameter than any other barrel, they also use a proprietary bucking. I believe a g&g gas m700 upgrade bucking might work tho. I also swapped the metal ball bearing nub to a cut in half solid aeg nub. At about 120psi and the full length long barrel version of this installed I get 1.2 to 1.3 joules. At 150psi I got 1.6 but I'd be afraid of the thing exploding xD. I had to file the valve as the high psi (120) pushed it out to far and blocked the feed ramp from returning. It is also possibly to replace the hammer spring with a stiffer one if you can find it.

"Honestly not as good as I'd hoped the gas injection is underneath the suppressor which means I have to take the suppressor off every time just to load it with green gas. But at least when it shoots it shoots nice and it feels nice it's also really heavy honestly this is more of a showpiece than it would be practical as loading the gas is the biggest negative.

"looks amazing but doesn't function
I bought this at the warehouse out in Cali and didn't use it for about 2 days ( had to wait to get the gas for it) then when I finally filled it up and loaded it I went to cock it and it jammed up instantly and it did it so bad that now there is a BB stuck somewhere in the receiver to the point where I cant get it out or even close the chamber so the gun is useless before I ever got to shoot it total waste of $300 don't buy this gun
