Radical Firearms 5.56 AR-15 Barreled Upper Receiver - Slim M-LOK Handguard - BMD Flash Hider - 16"

A quality product. Well made. No issues

Charging handle wouldn’t pull back all the way and to get it to pull back I had to persuade it pretty hard. After I started messing around with it some more I noticed the feed ramp is out of spec and was taking chunks out of the tips of the rounds. I ended up throwing my LMT BCG and Radion CH and it didn’t even move. Pretty trash upper. Customer service got me squared away pretty quickly though.

I became a regular client of PA for one reason: they package and ship while you pay for it. I received all my orders in a matter of 2 days. Other vendors take 1 week for processing alone.
As far as this upper, I've bought 4 so far to fix my pistol brace issue. You can’t go wrong with that sale price.
Excellent packaging, sturdy hand guard, acceptable finish.
You will not find a better value for the price at the moment.

Amazing product came safely packaged! also I love the detail that it came with stickers. 10/10 quality worth for a Budget AR-15 5.56 build strongly recommend this complete upper!!!! GREAT QUALITYYYYY!

For $189.00 this is the BEST value for that price even if the price was higher. Bought this not expecting much honestly but, I have to say, for this price, this is top notch. If you're considering buying an upper or you would like to dip your toes into buying and building your own AR-15 then, this is the way to go. If you purchased the cheapest versions of all the parts on this separately, you'd still pay about the same and you wouldn't be getting anything near the quality this one has. I'm a gunsmith, 20+ years of experience, I build Ar's from scratch all the time and I have to say this is IMPRESSIVE! If I were to purchase individual items using my wholesale prices that are a match to this upper, it would cost me more than this upper and I'd have to do the work of putting it together. (Not that it's hard for me to put them together having built so many but it's, no extra work AND a lower price) win- win

Over the years, I have purchased several Radical Firearms uppers. Each time the build quality and durability was impressive especialy for the price.
Primary Arms shipped both super fast.
No complaints.

I just got this on Saturday. Fast shipping. Looks great. Everything dropped in from my other rifle very nice. Haven't fired yet, but going to soon.

After changing to light weight bcg, multiple springs, different lowers, and different ammo, still short cycling.

Looks great feels great now I just gotta try it.

Solid upper with the slim hand guards and BMD flash hiders. Units were well packaged for shipment and arrived quickly. Finish is perfect on both uppers and components are installed perfectly. Bolts and "T" handles installed easily and locked up beautifully. I have not had a chance to fire them to test accuracy but believe they will shoot just as good as they look. Thank you for a pair of solid quality uppers for an excellent price and reasonable shipping costs to boot!
