Most Helpful Positive Review good upper, bad shipping.
I really like this thing, it is lighter than my other pistol upper, though at 100 yards it has a wider group (.5 inch wider). the fit to my lower was tight with no wobble and it cycled just fine with a regular carbine buffer without error, both sub and supers. makes a good truck gun, though I'd trus...

Most Helpful Negative Review Still waiting for my upper
Ordered in Jan 2018, still waiting as of June 2018. Don't expect to get your order in the same year you place it. After calling and speaking to a representative who assured me the item would ship by the end of February, i have little faith Optics planet isnt just selling items they can't actually ge...

Completed Upper for AR Pistol Build - Very good quality

by Kevin Kelly, Verified Owner from WI, United States Written on March 3, 2022
The packaging was great for this particular part. No blemishes or defects.

The fit and finish perfectly matches my PSA Pistol Lower assembly.

The bolt did need some additional lubrication, but a proper cleaning and lubrication should be completed on all new parts.
Pros:
  • packaged well
  • Fit & finish, looks great
Cons:
  • None
Best Used for:
  • ar pistol builds
Would recommend: Yes

Not a bad little thing of metal... Decently impressed

by JJ, from CO, United States Written on November 19, 2019
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.
Pros:
  • Looks amazing
  • Build
  • Budget
Cons:
  • Rail Screw Quality
Best Used for:
  • SBR
  • ar pistol
  • Home defense Build
Would recommend: Yes

Excellent Upper

by Brian, Verified Owner from MO, United States Written on November 9, 2019
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.

very rough finish with blemishes

by Brian Womack, Verified Owner from OK, United States Written on May 5, 2019
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.
Pros:
  • Price
Cons:
  • Blemished finish
Would recommend: Yes

300 BLackout build

by Dave, Verified Owner from GA, United States Written on March 29, 2019
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.
Would recommend: Yes

Solid for price

by Chris, Verified Owner from MO, United States Written on November 11, 2018
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.

No issues with this upper

by Ed, Verified Owner from FL, United States Written on October 15, 2018
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.
Pros:
  • Works with SilencerCo Omega
Cons:
  • None
Best Used for:
  • suppressed shooting
Would recommend: Yes

Nice shooting LITTLE piece of equipment

by Sgtpbone, from KS, United States Written on July 29, 2018
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.

Excellent Option

by Coly, from SC, United States Written on March 16, 2018
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

Don't buy this upper

by Don, Verified Owner from AZ, United States Written on January 23, 2018
Improperly installed gas tube ruined 2 gas keys. Rifle fired approx 200 rounds before it started failing to go into battery, i tried a new bolt/carrier which is how the second bolt carrier key was ruined. I then noticed how the key was marred and looked at the gas tube...

Get any other upper from any other manufacturer. Optics planet should stop selling from this manufacturer.
Pros:
  • None
Cons:
  • It will break your bolt carrier
Best Used for:
  • paper weight
Would recommend: No
