I am in the process of building an AR-15 right now. When I was shopping for uppers, I came across Parallax Tactical’s PWT Extreme Uppers and was blown away by their components and price. These are some high value uppers.
The heart of any upper is its barrel. Parallax Tactical uses barrels from Black Hole Weaponry that have been made to their specs. They are 416R stainless barrels with 1 in 8″ polygonal rifling chambered for 5.56. The barrels are Melonite treated which stainless steel barrels benefit from in a number of ways like increased barrel life and a more subdued appearance.
Parallax Tactical fits one of their own rails like their FFSSR or FFSSR KeyMod rail. The rails are available in a variety of lengths. You will find one of Parallax Tactical’s Super-Lightweight Low Profile Gas Black under the rail and the barrel appears to be dimpled to prevent the gas block from rotating.
The bolt carrier group consists of a standard black phosphate 8620 steel bolt that has been MPI tested. The carrier is also 8620 steel and Melonite treated. You can upgrade to a full NiBX treated BCG if they are available. The gas tube is also Melonite treated.
The barrel is capped off with one of Parallax Tactical’s Paracomps with is machined from 17-7PH stainless steel and Melonite treated.
To top all of that off, Parallax Tactical is a full service shop that offers coating services and a full line of accessories. You can basically look at these uppers as a starting point and build from there. For instance, I wanted a different barrel profile than the standard M4 profile that was offered and they were able to accommodate. They also Cerakoted the entire upper FDE for me.
Check out PXT Extreme Uppers at Parallax Tactical and stay tuned for a review once I am able to put rounds downrange.
