Great looking BCG and seems to be very well made. Can't wait to finish my build so I can try it out.

Great Product


I put this in my custom 5.56 SBR 10.5" build. Using a JP Silent Spring with it. Everything works great together. Ive shot around 40 rds unsuppressed and 160 rds suppressed. Works great cleans up well. The bolt feels very smooth. On the instructions you need to pretreat with lube that is provided with the BCG in the package. I did this and then cleaned it off and applied CLP.

Holy cow


Man this thing is slick and not just in the design but to the touch as well I love the added geometry of the bcg as well as the look of the lighting cuts the finish is superb and is completely devoid of anything resembling a tooling mark gas key is well fitted and staked it looks like they really took their time coming up with this and I can't wait to see how it runs on a side note maybe it's just me but the supplied froglube seemed like way more than needed was able to lube my whole rifle with it which is a huge plus or I'm not using the required amount lol

Works as lantac advertises


Purchased BCG for suppressed 300AAC SBR. So far this carrier has lived up to the manufacturers claims. It does vent gasses forward, recoil impulse is very improved, fit within the upper is tighter/better, finish is slick. Machining is excellent, it's NOT covered in tiny machining scratches. I can not attest to cam pin, old upper beat up already. I have not tested accuracy yet. Overall I'm very happy and impressed with this carrier. I have shot many carriers in my blackouts trying to find a carrier that improves realibility and performance so far this carrier has done both. Hopefully over time the carrier and finish stand up to the abuse. First time doing business with primary arms very good experience I will be back again.

Very satisfied customer


What can I say, Primary Arms is an exceptional company to do business with! Prices are great, communication is first class and shipping is immediate. I am beyond impressed with Primary Arms and I look forward to continuing doing more business in the years to come.

Awesome Experience!


You guys rock!! Great inventory and selection for high-end AR builds!

Works as advertised!


After installing this I noticed a slightly softer recoil impulse and no wear on upper from cam pin after 200+ rounds. The coating also makes it a dream to clean. Excellent product and service! Will be buying another.

A really nice, but expensive BCG


Picked this up during the holiday sales to replace a basic phosphate YHM BCG. Machining and finish coating are pretty close to flawless. Headspace checked with Pacific Tool .223 Wylde gauges was as expected on a NorthTech Defense Barrel.

The rounded cam pin may reduce wear, but after 300 rounds it is too soon to tell. It was a pain to remove the it first few times. It is slick, round, and tough for larger fingers to twist, the flat side is your friend!

Cleans up extremely quickly, which was my primary reason for picking it up.
I noticed no change to accuracy or recoil (this was already a sub MOA rifle).

Charging the weapon does feel smoother, but that may just be my brain trying to make my wallet feel better.

I'm happy with it. I personally like the way it looks, the cleanup, everything. I am aware, however, that this is a luxury item, you don't need it, but it is very nice to have.

Best BCG on the market


This is by far the best BCG that I have ever used. I love the forward facing gas port!!!!! It does an amazing job of keeping gas out of my face while shooting suppressed!!!!!!!!!!

Enhanced BCG


This is the highest quality BCG I have used. I was going after another Young NM group but they were OOS. The NiB coating is superb and I'm digging the smooth cam pin design. It runs great in SBR's and suppressed rifles. It's permanent home is in 16" RECCE style rifle that runs suppressed. There is no other BCG that I've seen that mitigates gas as this one does. Yes it's pricey but worth it if you are doing a high end build and demand the best components.
