PLEAE READ ALL INFORMATION PERTAINING TO OUR BOLT CARRIERS AND DISCLAIMERS:

Bolt Carrier due to the polymer buffer is not compatible with most folding stocks.

It is compatible with Shield Arms Folding Lowers
Compatible with Law Tactical Folding Stock with our Proprietary Folding Adaptor, Part # 251015
Compatible with Sylvan Arms Folding Stock with our Proprietary Folding Adaptor, Part # 2510152

JP Silent Capture Spring is not compatible with our bolt carriers. In order to use JP Silent Capture Spring, the end-user would need to make modifications to the carrier's integrated buffer.
Armaspec Stealth Recoil Spring is not compatible with our bolt carriers and bolt carrier polymer buffer can not be modified to work.
Some off-the-shelf rifle cleaning solutions such as Hoppe's #9 can react negatively with NiB finishes. Since our carriers have nickel-based coating these should not be used on NiB/EXO coated products. Always refer to the manufacturer's recommendations before use on NiB/EXO coated products.
Our Select Fire Customers have stated carrier bounce has been eliminated due to the polymer base buffer.
We have run select-fire and have not experienced carrier bounce since the introduction of the integrated polymer base buffer.
Patented buffer technology has been in use since 2010 with over 20,000 rounds without needing to replace the polymer buffer; however, if one damages the polymer buffer it is easily replaced.

Mr.

Singularly the best BCG I've ever run & I've run them all. I ran this at the range today using everything from premium U.S. made ammo to rotgut combloc steel cased ammo almost 50yrs old. Not one hiccup. I run this bolt with a CTS 'AKTIVE' ANTI-TILT Recoil Buffer in and out of a Strike Industries Mil-Spec/Com-Spec Hybrid 7 position tube, all married to a Ruger SR556 lower. I cannot believe how smooth and silent this bolt works with that buffer; no spring rattle, no buffer rattle or wobble, no scraping of the tube walls - incredible BCG. I just learned of your company two weeks ago and I've already bought two - this one in 556 and one for the x39. I'll be back for more. Happy Holidays!

Bolt's performance

It is amazing, the feel of the rifle and how smooth it is. With the elimination of the carrier bolt tilt(Something I never really thought about) it's so simple yet it makes a world of difference. I would not get another type of BCG ever again. I want to get a complete upper after this.

Q: Will this BCG function reliably with FRT use?

Asked by: Steven - 6/17/2026

A: FRT's get light strikes due to carrier bounce and our carriers are not only compatible with FRTs, but helps mitigate carrier bounce. Here is our video of Charles showing an all steel carrier and our enhanced carrier running FRT and how our enhanced carrier runs reliably versus the all steel carrier: https://www.youtube.com/watch?v=FPKU50Uht3I&source_ve_path=OTY3MTQ&embeds_referring_euri=https%3A%2F%2Fwww.blackriflearms.com%2F

Q: Any plans to come out with ones that are cerakoted or have a phosphate coating?

Asked by: Andrew Martin - 5/12/2026

A: We do not; however, if one wanted a cerakoted bolt carrier we could cerakote the carrier and key with Cerakote E-100 Blackout as a custom order. We only recommend E series on an application like this and cerakote guy charges $65 for just the bolt carrier and key. The small parts are already black and is not included in the pricing.

Q: In comparison to a standard BCG, what is the typical drop in decibel level?

Asked by: Jamie - 9/16/2024

A: There is no difference in decibel level which has nothing to do with felt recoil.

Answer provided by: Administrator (9/24/2024)

Q: Just making sure, this bcg will work for 5.56 nato, 5.56x45, 223 rem, and 223 wylde?

Asked by: Jake - 7/18/2023

A: Yes it will with them all.

Answer provided by: Administrator (7/20/2023)

Q: I realize your disclaimer says no folding stocks but was 17 designs folding lower tested? It doesn't require anything to be inserted into the BCG. It’s extension is flat on the end like a buffer.

Asked by: Rob - 1/2/2022

A: We have not tested it, but from the looks of the design it looks like it would work. If you wanted to test the BCG with their lower to see if it's a go we would be happy to hear any feedback regarding compatibility. If it didn't work then we would just ask that you send it back and we would refund your money and waive the restocking fee.

Q: What is the difference between this item and the standard M16 enhanced bcg with buffer ?

Asked by: Harold Piskiel - 2/3/2021

A: The difference is this 5.56 Bolt Carrier Group is drop-in ready. The M16 Bolt Carrier would need Bolt Assembly, Firing Pin, Firing Pin Retaining Pin and Cam Pin. Hope this helps.

Q: Will this work in a 300 blackout di upper.

Asked by: Kay - 5/20/2020

A: Yes it will function fine with 5.56 or 300BLK calibers

Answer provided by: Customer Service (5/21/2020)

Q: Is this an anti-tilt design?

Asked by: Joey - 4/27/2020

A: The DI Bolt Carriers come with a standard integrated buffer which helps not only to eliminate metal on metal contact during the transition from upper to lower receivers, but it also buffers the impact between carrier and buffer. However, if one wanted to keep DI Bolt Carrier centered which mitigates tilt one would need to ask for a oversized buffer to install. Oversized buffers have a larger oversize dimension than the standard size polymer buffer.

Q: who is manufacturer of this bcg? aero precision?

Asked by: john d - 12/20/2019

A: We are the manufacturer of our bolt carriers. Our found/owner, Charles Cassels, holds the patent on these bolt carriers with buffer.

Answer provided by: Administrator (12/20/2019)

Q: Will this bcg fit ANY AR-15 and why should one purchase a “”spare bolt carrier buffer”? If you’re unsure of its functionality or usability then your company should include one with bcg purchase. Seems like the only right thing to do imo.

Asked by: K. P. - 8/22/2019

A: Our BCG will fit any mil-spec AR-15. As for the spare buffer, it has a lifetime replacement warranty if it were to malfunction/mfg defect, etc; however, customers kept requesting they could buy a spare so if something did happen they would have a spare replacement for backup while we replaced this part under warranty. While we have explained to customers we have never had to replace one they still requested a spare for their spare parts tactical box as a "just in case". Having never replaced one carrier buffer in 10 yrs of selling them indicates a pretty good functionality or usability testing. We have some spare buffers with over 20,000 rounds and they still look new, when designing this polymer buffer we used the best materials for this application and it went through rigorous testing.
