Barrel: A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as "Machine Gun Steel" by virtue of its use in FN's M249 and M240 weapons.   The hammer forging process work hardens the steel, making it more durable.  In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability.  Chambered in 5.56 NATO, with a 1/7 twist, M4 barrel extension, and a Carbine-length gas system.   Barrel is High Pressure tested, and Magnetic Particle inspected, to ensure quality and dependability, and is finished off with a 13.5" PSA Lightweight Keymod free float handguard, low profile gas block and A2 flash hider.

Exactly what I wanted!!
Fit and finish was outstanding! The quality of these FN barrels that PSA uses are some of the best you can get! The keymod forearm is very slim and light weight! I coupled this upper with an STR and EPT lower build kit and could not be happier with the end result!!

My Step Son bought one of these and overall it is a superb upper
Despite the "old wives tale" of chrome lining negatively effecting accuracy that has never proven the case with any quality rifle design be it AK or AR config. My Step Son recently acquired this upper and mounted it to a Windham lower and after burning a couple hundred rounds through it found that it was highly accurate for a carbine length upper. He has changed out his lowers trigger with a 3lb Timney and had great results with the 20" upper by Windham he had but he wanted a shorter carbine length upper for "brush work". I got to fire the configured carbine and managed very tight groups at 100 yards using the incredibly large EoTech 512 he had set up. The only negative he mentioned that I could barely see (the gun was a bit dirty but not overly so when I had my go) was some visually apparent tooling marks on the barrel exterior and some scuff marks to the uppers finish around the charging handle area. He didn't bother griping and thought the exterior marks could have been made by test firing and ejected shell impact but had no way of telling. Someone at PSA should have noticed both problems however as he did NOT buy a blem. Regardless the upper was more accurate than a Colt 6920 I had a LOT of experience with and there was no gaps when mated to the Windham lower. A VERY good upper overall. I now have one in my shopping cart that I placed there but when I placed it there it offered free shipping......which apparently has gone away and now I am looking at a $17 shipping fee. Still for basically an FN barrel that is chrome lined (a MUST for me as I am still not sold on the new metal "treatments"). The handguard is a real plus and it seems hard for the kid to not start hanging everything on the aftermarket on all sides of the carbine. So far he has resisted everything but a forward handguard with a built in tactical light. At under $400 this is an incredibly great buy it is just too bad that all but the most basic charging handles were unavailable when I went looking and found this upper and placed it in my shopping cart. I guess I will have to go elsewhere for one. I hope the reviews for the PSA BCG that I have also added to my shopping cart are correct and that it is indeed a very good BCG as for just slightly more I could get a nickle boron BCG from AIM.
