I ordered the "Davidson Defense AR-15 Nickel Boron M-16 Bolt Carrier Group Complete" from Delta Team Tactical FOUR days ago and it is here in my hands! I am impressed with the quality of the parts and the incredible smoothness of the coating on this piece. I have one from a company who specializes in coatings and it took some light cleaning/polishing to make it as smooth as this one is right out of the box. The machining is beautiful and the quality of the parts all make me very happy that I bought this BCG from the Delta Team. I took the BCG apart within minutes of opening it and everything looks incredible! This BCG is a great part and being at the center of action in the rifle I will feel more confident after seeing the quality of the parts. I am also impressed that the people at Delta can get things shipped so fast. If you are thinking about a BCG and want a coated one than go no further, order it from Delta and you will get the same great service they gave me!

Excellent service. I Talked to Glen in technical service. Quick shipping. Nice finish on this BCG. Gas key fit and headspace checks are excellent. Good value, I ordered another.

Fail Zero BCG
Great deal/Great product! I opened it up and put it in my M&P 15 (no lubrication) right out of the package and put 100 rounds through it. Zero malfunctions, just as advertised. I will run it with lubrication in the future, but I just wanted to see if the nickel boron was as good as advertised. I was impressed.

very nice piece!
The nib bcg I got was very nice and ran the first 250 rounds without a hitch. Very slick and has a very nice finish. Ran it in a Palmetto upper, looks good and would definitely recommend and will purchase again for my next build

Superb Bolt!
This is a great quality bolt. It is easy to clean and has run flawlessly thus far. I'm going to replace my remaining bolts for this one. Buy!
