What is the overall length of the barrel and flash hider?
michael m on Sep 10, 2019
Comment answered on the 10.5 barrel Pistol to be 26.5" barrel to buffer end. With the 11.5 barrel wouldn't that put it at 27.5" and put it beyond the Pistol length limit?

Is the BCG nitrided or phosphate?
Damien S on Sep 28, 2019
Does this make a complete gun or do you need other parts?
Donald R on Sep 12, 2019
BEST ANSWER: You would need a stripped lower receiver to have a functioning pistol.
Who makes the barrel and bcg for these? Thanks!
Travis C on Sep 7, 2019
BEST ANSWER: can't answer on the BCG, but all the nitride barrels for PSA are made in house for them by their sister company, DC Industries (PSA bought out DC industries a few years back, so they make all their own barrels anymore but the FN CHF ones)
Is the gas block pinned?
Anthony L on Sep 16, 2019

No, this gas block is secured using two set screws in the base of the block.

Great PDW
Getting good accuracy and the 11.5” barrel gives me decent velocity. 75 grain Gold Dot 2650 fps muzzle velocity. Will work up a load especially for it soon enough but this makes an awesome truck gun.
Built this with a PSA Betsy lower, Romeo 5 red dot, magpul BUIS, factory enhanced polished trigger and Blue Force Gear sling. The trigger seems better than other EPT’s I’ve replaced in the past, no creep and maybe 6 lbs. think I’ll leave it for now.
Personally, in my opinion anything shorter belongs on a 300 BO or some other pistol caliber. I’ve spent thousands of dollars with PSA and have been well served with few exceptions.

Perfect HD/SD
11.5 barrel is the best!! Getting good velocities.
Great home defense / self defense AR. The size is perfect
Fast shipping, everything packaged neatly. Put with an Anderson stripped lower. Runs brass and steel 100%
Very light weight. The polished trigger really lets you get off some fast shots.
CONS: if i had to find something negative about it the only thing is the handguard was crooked. Easy fix . Also that i should've bought 2 of these kits lol.
