Most Helpful Positive Review Great Lightweight BCG
I am very happy with this BCG. So light and a really unique design. I put 500 rounds through it last weekend and it performed without any issues. Easy install. Well built and bolts properly staked. Really just a great lightweight BCG if you want to save some money on an AR build. Looks badass too. L...

Most Helpful Negative Review The one I received was defective
The BCG I received would bind badly in all 3 different uppers I tried it in. With a lot of force I could get it to go all the way in, but then it was nearly impossible to get it. I never tried to fire it and returned it. I couldn't see any clear defects and it otherwise looked to be good quality, bu...

Well made BCG

by Mikey, Verified Owner from NC, United States Written on December 29, 2024
I bought this lightweight BCG because it has the forward assist serrations and the seer trip. Also was supposed to be lighter than my AR Stoner lightweight BCG, but it's not. Also heavier than it's advertised in the specs by about an ounce. Have not fired a round with it yet but will update after a few hundred rounds.
Pros:
  • seems well built
  • Lighter than standard BCG
Cons:
  • Heavier than listed in the specs
Best Used for:
  • Range and matches
Would recommend: Yes

Recommended w/ Caveats

by ReviewThePew, Verified Owner from VI, United States Written on September 6, 2024
Good value lightweight bolt. Used in a 300blk build with good success even with dirty subs and heavy lube. Sand cuts seem to be solid. Need more rounds to test durability. Part of cam pin channel was chipped but did not affect reliability so far... Not ideal. Will keep eye on it as the round count increases. Gas key had extremely good fit with the gas tube I used.
Pros:
  • Lightweight
  • Sand cuts
  • Tight gas key seal
Cons:
  • Chipped cam pin channel
Best Used for:
  • recreational shooting
  • Suppressed
Would recommend: Yes

Great for my dissipator

by Sean, Verified Owner from AZ, United States Written on April 17, 2023
I got a delton dissipator and those builds are notorious for weaker gas, but very pleasant recoil. I got this BCG as it is about 30% less weight than a regular milspec bcg. It solved any short stroking issues I had and my dissipator cycles reliably every time while feeling like a bb gun. Thanks to this BCG, my dissipator is my favorite build. Even did a few mag dumps full auto and the bcg held up fine and the finish is still beautiful. No idea how the bcg would hold up for prolonged full auto use and I don't plan on putting it through any heavy abuse, but it runs really well and I'm very pleased. It probably will end up holding up very well because of how sturdy it is. It took a finicky build and made it amazing to shoot and just as reliable as any duty gun. It didn't exactly lend to any change in felt recoil though. Just made cycling better. I'd also recommend this if you're using weaker ammo and you have a really stiff buffer. Excellent price as well that won't break the bank.
Pros:
  • good price
  • reliable
  • Sturdy
  • Full auto profile
  • Beautiful look and finish
Cons:
  • Maker hasn't officially tested it for a guaranteed full auto rating
Best Used for:
  • Rifles with weaker gas
  • Low power ammo
  • Downtuning the gas for a lighter shooting experience
Would recommend: Yes

Great bolt carrier

by Bryan Savage, Verified Owner from OH, United States Written on March 17, 2023
Used it in a "lightweight" build and man it works. Barrel and bolt are the heart of any rifle. With this BCG you can know the bolt part is good. 1500 rounds on it so far. Cleaning ever 500 or so and no malfunctions. Finish still looks new
