I ordered and received several of these bolt carrier groups. I am very happy with them, but have one issue. The product listing for this currently says "Firing Pin Material: 416 Stainless Steel." However, I believe the military spec is for a chrome plated firing. I saw this before I ordered it, and decided to order it anyway. I thought the description might be a mistake. However, what I received does look slightly different from other "mil-spec" firing pins I have seen. Does anyone know if these really are (or are not) chrome plated steel?

I put together an AR pistol and used the Toolcraft Nitrided BCG from Monmouth based on the price, reputation of these, and the reviews I've read. This bolt carrier group is amazing. Gas key is properly staked, the nitride finish and metal surface if flawless. I just got back from the range and fired 40 flawless rounds through the new AR. Brass ejects into a nice small circle and is consistent. I'm extremely happy with my purchase and from now on will only buy Toolcraft bolt carrier groups from Monmouth, thank you!

I purchased this bcg to use in a new upper from Palmetto State to replace the Smith & Wesson sport two. I am no expert when it comes to the details of bcg's but it came lubed, smooth, and beautiful to the eye. The take away is it functioned perfectly with my hand loads of 55 grain to 65 grain in the Palmetto upper pencil barrel 1/7 twist mid length gas system with groups in all bullet weights I could not get close to with that S&W sport upper.

I couldn't be happier with this nitride bcg at this point in my ownership. I have only had the build complete for about a week and only have about 500 rounds down range but she is working perfectly. The staking is perfect and the coating is nice and even.

The BCG arrived quickly and is a solidly machined bolt and carrier. Nice smooth finish with no tool marks and properly staked gas key. Worth the money is an understatement!

Looks good, runs even better. Installed in a 8.5" 300 BLK pistol, ZERO stoppages or failures. Monmouth was a great company. REAL fast shipping, ordered Friday and received on a Monday. I had one question, received a response the same day from James. GTG. I will order from them again.
