Barrel: PSA 16" 4150V Chrome Moly Vanadium steel barrel, chambered in 5.56 NATO with a 1:7 twist rate, M4 barrel extension, and a mid-length gas system.  Gen2 PA-15 barrels come standard with a dimpled barrel to allow easier indexing and installation, as well as a more secure fit, of aftermarket gas blocks.   The Nitrided Gas Tube is a Mil-Spec Stainless gas tube so it is designed to withstand high heat and resist corrosion, and the Nitride finish helps the tube maintain a presentable finish for a longer period of time.  The Barrel is finished off with a PSA 13.5" Lightweight M-Lok Free Float Rail which features anti-slip set screws that help ensure the rail is securely attached to the barrel nut.  The rail also features multiple QD attachment points for slings.  Other features include the .750 low-profile gas block and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. These uppers are made for us right here in the USA by a mil-spec manufacturer.

 Bolt Carrier Group: ToolCraft BCG has a bolt made of mil-spec shot-peened Carpenter 158 steel. Gas key is secured with grade 8 fasteners and staked per mil-spec.

The complete barreled upper assembly shown on this page is different from the one shown in the video. The video shows a lightweight M-LOK handguard (picatinny at front and rear only, no QD mount on the handguard to barrel nut bracket) while the picture for the listing shows full picatinny on top & a QD mount on the barrel nut bracket. Which upper illustrates the actual product for this listing?
GreenD on Aug 13, 2019
BEST ANSWER: Called customer service today and was informed the item pictured is the item that will be received. The video is only of the general product family.
Are there any incompatibilities between the Gen2 upper and a Gen1 lower?
Tod P on Aug 13, 2019
BEST ANSWER: Nope. I have a gen 1 lower and works great. Also have an Aero lower and no problems there either. It should be compatible with almost any mil spec lower.
Pictures and video don't match product?
GreenD on Aug 13, 2019
BEST ANSWER: Product is as pictured. Video is just a demo with a different rail.
I know the GEN-2 barrels are dimpled, but do the gas block set screws come with red-loctite, or something equivalent? If so, please specify. Thank you!!
Adam C on Aug 14, 2019
BEST ANSWER: Well, if not Red LocTite, then 'something equivalent'. You're Welcome.!!
Will this match up to a Bushmaster lower assembly? Am new to ARs and would like to change up my baseline rifle. It is the Bushmaster QRC.
Jonathan F on Aug 16, 2019
BEST ANSWER: Do you have a typical Bushmaster lower?? Mil-spec and the like or do you have the 'double secret' Bushmaster?? If it is like the normal, tens of thousands have been produced, mil-spec, it will mate up because it is mil-spec... Virtually all mil-spec uppers and lowers will mate together due to the standardized AR platform. The issues arise in the AR-10 family as there is not a mil-spec version and manufacturers use differing templates, guides, sizes, etc. AR-15 family, go for it, mix and match.... AR-10 family, best to stay with the same manufacturer.
What tier of PSA barrel is this? Premium, freedom, unmarked/PTAC? I confuse, send halp!

CHARLES H on Aug 16, 2019
BEST ANSWER: anything stamped 5.56 will fire .223 fine normally you will never see .223/5.56 stamped on a barrel
