After opening the package it looked pretty good. I mounted it on a Sig pistol lower and went to the range. Things fed through it without an issue. For an inexpensive LITTLE piece of equipment it worked great.

Good quality item. Well built. Seems to have a durable finish. The guard could be better but it works for the price. The forearm would be nice if it came with snap on covers, again for the price it is a good deal.

I was surprised at how light it was when I originally picked it up. My entire pistol comes in at 4.5 Lbs. The rail is VERY sturdy and feels amazing. I also love the way it looks. My only complaint *so far* is the quality of the Allen screws on the rail. They are sub-par. I stripped one of them out almost immediately even though I was using the correct sized bit. I ended up needing to take a Dremel to turn the Allen head into a flat head. It is currently on its way to be painted and once it gets back I will throw in all the parts, attach my Form 1 and head to the range. So far, I suspect no further issues from this upper/barrel.

Was looking for a good quality budget upper to put on a house gun and Radical has delivered on all aspects beyond expectations. Excellent product for the specific needs I had in mind. If you need an excellent upper with quality rail systems, look no further

The finish is pretty rough and the upper has a lot of blemishes. I recommend applying a cerakote or Duracoat to the upper. I do recommend the product for a cheap build, just wish the finish was better.

I have been trying to shoot 300blk suppressed and this upper did just that. This upper has worked flawlessly with different types of ammunition both supersonic and subsonic (with a suppressor). It cycles properly each time regardless of the ammunition.

1,200 rounds, no malfunctions. Running with a Spike’s Tactical BCG & Spike’s Tactical H2 Buffer. Paired with an Anderson lower. Functions perfectly. This is a great value without sacrificing performance. I would recommend to everyone.

Runs flawlessly with Remington 120 solid, Hornady 110 Vmax. Excellent accuracy using a Sig Romeo 5 at up to 50 yards. The only issue I have had is using Sellior and Bellot 220 grain subsonic which will not cycle more than once. I do not have a can on this build will try some different sub sonic loads loads.

Solid quality for the price. The barrel nut screws suck all though I mean they work but i can see the potential for stripping easily. Handrail was nice and slim. Very slim profile overall.Gas block is pinned which is awesome.
