Expert Review

Functional with subsonic and supersonic 300 Blackout loads, basic blaster, good performer

by Stevey GB, Gear Expert from TX, United States Written on June 12, 2023
I have this upper to shoot all .300 BLK ammo. I got the complete upper with basic black nitride coating and A2 bird cage. Shoots sub and supersonic loads interchangeably without a hiccup. Solid handguard with M-Lok slots for accessories. This upper has installed on it the TRYBE DIMA/LEO scope/rangefinder combination and it's the perfect sighting instrument to use with the rainbow trajectory of slow subsonics. I love the versatile .300 BLK cartridge and it was the best way to get into an reliable upper without breaking the bank. I keep my nitride guns on the wet side and recommend we all do. I've found no extraordinary BCG wear during cleanings, everything looks happy. Good solid performer to blast this great modern little 30 caliber cartridge.
Most Helpful Positive Review 300 blackout
Awesome product. Love that the hand guard had tabes, so if for some reason it come loose it won’t spin on you. Flat black color no sine and awesome hand guard Design. Also like it comes with a bcg and charge handle.
Most Helpful Negative Review Small inconsistencies
The receiver was marred and scratched, dust cover was coated in sticker gunk and scratched badly, had to file down the rear pin tab to make it fit, not marked trybe anywhere (barrel is marked by another company), charging handle doesn’t fit quite right so it scratched and gouged when I was oiling ev...

Did not come with BCG and charging handle like it said it would

by James Smith, Verified Owner from AL, United States Written on January 2, 2025
First off it says 2 or 3 times in the description that it comes with mil spec BCG and charging handle and it didn't and that's the main reason i bought this particular upper. Second off i put this upper on 3 different lowers i have with the correct charging handle and it failed to cycle every single time on every one of them. I guess you get what you pay for.

Trybe AR15 .300 upper

by Luis S, Verified Owner from TX, United States Written on May 1, 2024
I purchased this back in September 2023. I swapped it between three different lowers and it fails to cycle 110 and 150 gr rounds. It fails to extract and causes the following round to jam with the spent round. It cycles 200gr well, but leaves a lot of brass casing residue. Not impressed. Will not buy this brand again.
Pros:
  • None
Cons:
  • Not the best finish.

feedramps rough and sharp

by ETXDMRguy, Verified Owner from TX, United States Written on April 2, 2024
I like the upper but not for your 1st AR. The ramps were sharp and rough and needed to be polished. I tried to contact Trybe but no support from their website.

Good upper

by KSrocks, Verified Owner from MT, United States Written on December 22, 2023
Anchor Harvey Aluminum Forging receiver, barrel marked with .300 blk, comes complete with BCG and charging handle, and fired 80 rounds no problems right out of the box; it was very well packaged. Highly recommend. Price rose $20 immediately after I bought mine. .300 blk is a blast to shoot. Thanks.
