Ratings & Reviews
Great value, super slick.
I caught one of these on sale a while back to throw in a budget build to replace a disappointing "Premium" model from a well known shop. The nitride job was easily better than Hodge bcg I have, the domed cam pin is a sweet bonus. Well staked, no machine marks, great coating, highly recommended for the price. I took it out of the budget build and put it in my Recce.
Great Product, not guaranteed material

When you can get these on sale, best BCG for sub 150 you can get, extremely smooth and well made. Only downside is normally they were sold with 9310 bolt, now they are dependent on stock, and do not specify which bolt material you are getting: carpenter 158 or 9310.
If you get the 9310 you are definitely getting a great deal, if not, it is still a great option for your build.
First one I bought was for a build I did for a buddy. I was so impressed with how the rifle performed I bought another one as an upgrade for my mk18. This BCG is super smooth, easy to clean, and hasn’t caused me any malfunctions the mk18 bolt was causing. I would strongly recommend this BCG to anyone. I’m actually about to buy another one. Don’t think about it!! just buy it because some guy who identifies as an A10 on the internet told you to!!
One of the nicest finishes I’ve ever seen. Incredibly slick and easy to clean. Used for an 11.5 aero. Epic Bcg
No brainer on sale!

Snagged the BCG when it was on a great sale. Smooth run and easy clean. Staked well and backed by a great brand. Definitely recommend. I think there are other better selections when at full price so grab when on sale.
Picked one up when it was one sale, saved a chunk of money and it worked well. Made a .300 blk out with only on sale parts and it turned out really good. I might have to pick another one of these up if they ever go on sale again. Clean construction and solidly built, no scuffs on arrival and PA ships super fast as always!

Bought this on sale, worked out better than I expected and I should've bought the limit of 3. Used in a .300 blk out, no issues dumping mags.

It’s a Lantec so it high quality. Staking was perfect and great cam pin. Got it on sale and what a deal. I’m very happy with it.

It's a great mil-spec BCG. Looks good. Runs great with no problems. I highly recommend catching it on sale like I did. It's nothing fancy, but runs great.
