Reviews & Ratings for Andro Corp Industries M16 Hard Bolt Carrier Group — 22 reviews — Page 1

I was a little hesitant in purchasing a TiN BCG as I have heard mixed reviews on the reliability. When I received the BCG though I was impressed with the for and finish. Checks all the boxes for me and so far has performed flawlessly. Hopefully the reliability continues long term but so far well worth the amount paid.

I bought this Gold Bolt Carrier Group, for my AR, and it really likes nice.
I just wanted to dress it up, so I put several parts into it, that are GOLD
color, and now it really stands out. I did this just to show it to my son in law,
his son, my grandson. And they loved it.

Received my TIN BCG and looked it over. Found that the carrier itself was riddled with machine marks, inside and out. The channel that the bolt rides in was not TIN coated and had pretty deep machine marks; causing lots of resistance on the bolt movement and would likely cause premature gas ring wear. I found the cam pin channel to be the same, uncoated and riddled with machine marks. On top of that, the description claims the bolt is MPI and HP test, however the bolt is not proof stamped as such. So you are stuck taking their word for it that it was indeed tested. Further, the bolt on this BCG is 9310 alloy which is dependent on very specific heat treating in order to obtain its strength rating (unlike C158). If the Heat treat process is done right, 9310 can be stronger than C158; if done wrong, it’s significantly weaker than C158. With the lack of attention to detail on the rest of the BCG, I am unwilling to risk using this BCG in my rifle because if they aren’t willing to pay attention to the details in their machining, coatings, or test stampings, what is to say they will pay attention to the details of their heat treating. Aside note, I have low end PSA BCGs with significantly better machining than this one. So it is not just me being picky. To make matters worse, when I spoke with someone at Andro and showed him pictures of the BCG in question, he claimed that all his BCGs looked that way and that they don’t proof stamp the TIN coated BCGs. So, while I only have a sampl...

After only 150 rds of 300 blk supersonic, the bolt completely jammed up and destroyed my upper, I have used every possible method to get it out but I have been unable to get out of lockup from my upper to try and figure out what ent wrong

I bought this a year ago and went through a lot of rounds. It's always eating to clean. Just wipe with a rag and the carbon is gone. Doesn't jam or rust. For the price, it's a steal.

I highly recommend this. Goodluck and have fun.

Have about 1000 rounds through this and coating still looks new after a good cleaning. have had 0 cycling issues. Like the color and is a good visual indicator of open bolt. It is high gloss so it might not be for everyone looking for that tactical advantage.

As I ordered ammo and this BCG, a backorder of 6 weeks later, the BCG wss finally in my newly built upper.

This upper was built for CQ drills with increased volumes of fire, and as a back up to my DDM4V7 upper. My build has a Wilson Combat .223 Wylde 16" barrel mounted onto a BCM receiver, shrouded by a Ripcord Industries handguard and an A2 flash hider.

This BCG hopped into the build, went through about 500 rounds each month since February. This month, I reached about 1800 rounds and I felt compelled to relay its merits.

The finish on the bolt carrier's rails left at around 700 rounds. The bolt lugs have lost their finish for the most part. Besides that? It's been absolutely solid. Yes. Nickel Boron, Diamond-Like Carbon, and Titanium Nitride are absolute market fodder. Their necessity on duty builds is arguable. If you want a solid BCG, go for Daniel Defense, or Toolcraft.

Otherwise, Andro Corps is an absolute solid BCG.

I have two of these and I love them both. I did have to return one because the quality control check done on it wasn't very good. The bolt was extremely rough in the carrier, the finish was subpar and it looked like there was a machine marks all over it. Optics planet was great with the return and I got a much better one the second time around. I've shot various bolts suppressed and this is the easiest one to clean by far, you can pretty much just wipe all the carbon away and then little bit and be done. I'll be ordering a few more of these for my next builds.

I have no complaints on the Andro corp bcg Looks great. Feels great and shoots great. Easy to clean I’d buy another. .

I just received it today and this coating looks great. This is a high quality bcg that's selling for a great price. I took it apart and viewed everything from piece to piece. No flaws. I will be using this on my 300blk 7.5 barrel with a silencerco omega 9k suppressor. This is by far my best set up. Can't wait to shoot.
