DESCRIPTION
 
AR-15 BOLT CARRIER GROUP 5.56 & 300 BLACKOUT BCG - MELONITE NITRIDE

Melonite Nitriding treatment turns a standard chrome moly steel barrel into a very lick, hard and corrosion resistant barrel. Unlike chrome lining, the Melonite process is a treatment done to the surface instead of adding a layer of material. This treatment is done to both the inside and outside of the BCG. The slick surface will never peel, is thicker than chrome lining, will not negatively affect accuracy as chrome lining does and will reduce the amount of friction created. Less friction equals less bore surface wear which will extend the barrel life. Another added benefit is carbon does not easily adhere to this surface making your cleaning job that much easier. This technology has been used by Glock, Springfield and Heckler & Koch for years and is gaining popularity as more companies are offering their products with this treatment.

1 of 5 Forced to purchase January 10, 2023
: John Martin from Dayton, NV United States  
MAS defense didnt tell me that their 18 inch barreled upper wouldnt function correctly if you didnt use a semi profile BCG. Hard to find elsewhere because nobody else uses them. BCG works like it should but still didnt correct BCG cycling problem with the MAS defense barreled upper. The support department was useless/ didnt help correct in any way.

MAS Defense Reply:  John, Your barreled upper using a Ballistic Advantage barrel was assembled using our 50 point checklist, head spaced and test fired to ensure 100% function before we sent it to you. We received your email advising of the problem and discussed several trouble shooting methods via email. We sent you an RMA label on 12/6 to get the upper back. You sent us an email on 12/21 stating you drilled out the gas port on the barrel and would not be returning it. We build thousands of uppers every year and provide our opinion on what the best parts to in combination with the upper would be. The upper should function with both a Semi and Auto profile BCG. Enlarging the gas port to flow more gas would fix the issue but should not have been necessary.
Thank you for your business and your feedback!

5 of 5 BCG Works flawlessly December 8, 2022
:  
Had a previous BCG that was faulty and wasn't ejecting from another manufacturer and needed something more reliable. I couldn't have picked a better one if I tried. Shipping was fast and it works perfectly. Amazing product.

5 of 5 Good value, looks great September 1, 2022
: David Stevenson from San Antonio, TX United States  
The nitride finish looks great in my opinion. The MAS logo even looks nice and I'm usually not a fan of branding. Would buy again.
