The last few months Nick and me have been running the G&P gbbr's with no problem with the internals, just with our rail/ris system and magazines, it takes about 30 seconds of gas filling along with tighten up the screw in the bottom of the G&P pmags overall the gbbrs are doing good. Now Tyler had used a spare gbbr that is forsake with no problems waiting to see how they do during the winter months

As the few that had use of the G&P GBBR's it has been noticed that the bolt doesn't closed completely sometimes causing misfeeds and lost of gas in the magazine. It appears that the stock buffer springs may be too weak, after installing a 140% spring and shot about 15 mags through it without any misfeeds or loss of gas

Also the G&P PMAGS, when buying these mags, remove the bottom plate and remove the pin with 5/16 pouch becareful as the keeper has a spring underneath, once remove take a straight slot screwdriver and tighten up the screw, this will eliminate the leaking seal that appears mid way of the mag after the first couple uses.

The Stainless steel 6.03 tight barrel is still little over size for the G&P Hop up, with little sanding you will be able to install the barrel into the hop up unit. it's very easy, don't get discourage

Better make a 130 spring and not a 140 spring, first gun did great and other two gabbros not so good, bolt would not lock back
