jtallen83 Posted December 18, 2015 Author Report Share Posted December 18, 2015 80 rounds this morning, 24 degrees 20 mph wind. 3 failure to ejects in the first 10 round magazine of ZQ1 M80 ball clone. Changed to adverse for 20 rounds with no issues but you can sure feel things getting slammed around. Tried some POF M80 clone with the same failure to eject results on the regular setting but functioned on the adverse setting. Tried a few rounds of Radway Green linked M80 ball and it functioned on the regular setting. I plan on testing a bit more over the holidays but won't be spending too much more on "testing" ammo.Conclusion...she's a picky bitch that is only going to function reliably on the adverse setting or with hotter ammo. I was hoping this "pistol" could be a SHTF weapon that would eat whatever was available for it but that doesn't look like it is happening. This has solidified my low opinion of piston 308 guns since I have two other DI 308's that eat whatever I feed them without issue, over 3,000 rounds in my AR-10 and not one failure! There is something about the piston system that seems to require a much narrower pressure range for reliable operation. Looks like I'll be looking to trade this P716 off for a 308 DI "pistol", hope the ArmaLite version gets out into the market soon........might just have to build one.

Charlie Posted December 19, 2015 Report Share Posted December 19, 2015 I thought I might be interested in it for a rifle conversion but: 1. No uppers available, and 2. It's a pricey sucker, and the rifle version costs $150 less. Weird!I haven't seen any piston AR type firearms in the wild. How do you tell if it's piston or DI if you can't see the gas tube?

jtallen83 Posted December 19, 2015 Author Report Share Posted December 19, 2015 My guess is the extra $150 is for all the repair work they know they will be doing on the ones that get run hard!In person you can clearly see the operating rod through the rail, much thicker than a gas tube.The extra weight is a dead giveaway as well as the carrier; Quote Link to comment Share on other sites More sharing options...
