Black Rain Ordnance SPEC 15 SERIES Black Nitride Bolt Carrier Group

Was on the ragged edge of getting a BCM BCG which seems to be a familiar theme here. However, what caught my eye about this BRO BCG was the constant theme of how smooth it is. Gotta say, this thing is slick! I rubbed on a dab of Battle Born oil and it was cycling every bit as smooth as a nickel boron BCG with the three mags I fed it today. I will write an updated review after I put a thousand rounds through it, but so far, this is my new favorite BCG. Bring the rain, baby...

Better then DD. I purchased this after ordering a DD BCG and selling it. Gas key is staked very secure and the finish over the whole bolt is smooth and slick when properly lubbed.

Very nice looking BCG. I confirmed with Black Rain that this is MPT and HPT. Get one

This is a 5000rd + update to my original review. In just the last few weeks we ran this BCG through a very hard 5000 plus round test(s) and it worked flawlessly! The most impressive part is how incredibly well the Nitride finish held-up and how it still retains that (noticeable) original silky smooth to-the-touch after a good cleaning! Black Rain's quality & attention to detail (at least with this BCG) is simply outstanding and easily compares to the best available, a fact not said lightly. I've been waiting for Primary Arms to restock Black Rain AR Barrels (hint, hint) because if the barrels are anything like these BCG's, you know the rest. Well done BRO... and please Primary Arms, get a few Black Rain barrels in so I can do more testing/reviews here, thanks!

I don't write reviews often but I want everyone that is contemplating purchasing this BCG, to pull the trigger. This is quality product. Ships in BRO packaging, not lose or wrapped in paper. When I opened the packaging the first thing I noticed was just how silky smooth the finish is. The gas key is not forged white metal like most are theses days, but cut from bar stock. Functions flawlessly

Impressive...<br><br>The first thing that strikes you when handling this carrier group is that it screams quality, very high quality.<br><br>The Black Nitride is simply flawless, extremely smooth (silky to the touch), having a rich deep black finish.<br> <br>Gas Key is made from Solid Billet and properly/professionally staked. (Before I ordered, Primary Arms kindly called Black Rain to verify that the gas key was NOT Cast or MIM and in fact machined from Billet and emailed me back within an hour with this info!)<br><br>It is a full auto profile for those that can't tell from the images.<br><br>Bottom line: I have owned & used hundreds of AR15/M16 BCG over my 40+ years training/shooting and this is one of the best I have handled/inspected "right out of the box". <br><br>If it runs as good as it appears.... well you know the rest.<br><br>Will update this "first impressions" review in about a month after over 5k rounds of hard use.<br><br>Thanks again Primary Arms for an unbelievable sale on this BCG ($109.99!).

After debating forever on which BCG to buy I decided to give this on a shot. I could not be more thrilled with my decision. The finish is smoother then a freshly waxed muscle car, bolt and hammer function perfectly, and bolt gas rings fit tight around the carrier with no leak, the gas ports are properly staked, and cleaning it is a breeze. If you are like me and want to keep it all black. Go with this one.
