M16 5.56 LIGHTWEIGHT BOLT CARRIER GROUP Reviews & Ratings

Went out and shot in my 16" and my 20" rifles, suppressed and unsuppressed. Not a lot of shooting, but after 500 rounds through both haven't had any issues. Look forward to many thousands more though it.

I bought this bcg, it gets dirty fast and you can't get the carbon all the way off the bolt, my only problem with the bolt was after the first 1000 rounds I had to change the gas rings, besides that it has been a good bcg.

the BCG was delivered quickly, and works. I wanted two things, lighter gun and lighter recoil. It did lighten my AR to 5.0 lbs, however the reduction in recoil I could not tell. but an AR15 has so little recoil anyway. BCG used on a PSA with faxon pencil barrel, mid length gas tube. I did not make any other changes and it worked fine. The prior full auto PSA BCG would eject at 3:00 and with this low mass ejects at 2:00 Maybe a bit over gassed. I was a bit confused not to see a chrome gas chamber in the carrier. I guess the nitride finish will do the trick, cleaned easily after 100 rounds.

Only complaint I have is that the tooling used for the firing pin needs to be changed out more often. The pin has bad tool marks and surface finish is much higher than others. First picture is one of my other pins second and third are this one

Ive purchased 5 of these 4 NiB and one TiNi. All ranging from 3k down to 250 rounds for the newest one. All oppressed as advertised right out of the box. Ive changed calibers/bolts on 3: 6.5Grendel, .300BLK, .450Bushmaster. All operate and only failures have been cheap ammunition or while tuning gas/buffer systems for optimal operation. Obviously I would recommend these. The best value in AR-15 lightweight BCGs. All had a black spring and a black puck on The extractor. All had ejector retainer pins that were properly seated. Gas keys properly staked. Bolt fit and gas piston to piston walls are a pass. All are average to above average gas efficiency. All finished are above average and show normal wear for particular caliber used and attached round count. Now to the not so great. Are they the best BCGs out there, no. Are they the best for the money, absolutely. 1st BCG was TiNi and the gas key firing pin hole was not deburred before coating and caused furring pin drag. Not enough to cause immediate failure but long term wear of the foreign pin would occur. So I cI deburred and polished. 2nd and 3rd BCG has no deficiencies. 4th BCG the bolt was the actual problem not the BC. The bolts key hole was not deburred on firing pin channel, entrance and exit which damaged my new LANTAC domed gas key. That ones really my fault for poor inspection before build and subsequent firing. Again, with the price of this BCG this problem is a non-issue to me as I made the repair. The average shooter would have only seen finish wear on the original gas key. My original gas key sits in the buttstock of the weapon. 5th BCG has no inspection deficiencies I noticed and is operating properly after I tuned my gas block. I wouldnt suggest using these BCGs in binary triggers as the sere trio face is unsupported and would likely fail. Just remember a light BCG is just a piece of the gas system and by only replacing it in your rifle will place it in an unbalanced state. Remember to address your buffer system, gas delivery and secondarily the muzzle device I do all simultaneously. Im a huge proponent of the JP silent capture buffer system used with a Superlatives (when theyre in stock) or Odin works gas blocks. The latter can be finicky if you done follow directions. All in all these are a good value but if you expect JP/Knights/BCM/etc fit/finish/quality youll be disappointed but not a whole lot. Do I see these as duty durable, no but a good choice for fun, occasional action match, home defense AND definitely LARPing approved for basement OPs, dont forget your NVGs, Boog Hawaiian floral and short shorts.

Used in 350 legend lightweight build. Used with Odin adjustable gas block. It worked fine so far. I liked the price point. I was skeptical, but I have no regrets. I do imagine I will have to fiddle with the gas block for different loads, but Ive accepted it.

I love the affordability of this product but you get what you pay for. This bolt carrier is lightweight but the coating for the nickle boron is either spot on or looks dull. I bought one of these around January last year and its smooth shiny and everything, but I bought one recently that just doesnt seem like it is coated in nickle boron very well. Great product. I still use them both and they perform flawlessly. I only gave this a 4 because of the inconsistency of the coating but other than that its a perfect bolt carrier group.

The BCG works great, have had zero failures and when paired with a flatwire buffer spring, adjustable gas block, 16" barrel and VG6 muzzle brake, this thing is the flattest shooting AR I have ever shot. The one major complaint I have with the NiB finish is it looked great when I bought it but after only a few hundred rounds, it has become very discolored and cleaning does not change this, even when using more abrasive cleaners. The carrier is basically carbon colored now and looks terrible. Not sure how TiN holds up compared to this but I would go with nitride if I did it again.

Bought this BCG for an unsuppressed 300 BLK carbine which had trouble cycling subsonics. The BCG appears well made and sturdy. The nickel-boron plating also looks well done. However breaking the BCG down for its initial cleaning, I noticed the plating on the rear of the bolt carrier did not seem to be as well done...tarnished, plus the gas rings looked a little sketchy. Also noticed the firing pin had mar marks, none deep enough to be scratches. Decided to go ahead and use this BCG. Solved my subsonic problem. Not so with higher velocity ammo...slam fired. Switched out the standard buffer for an H3 and went with a different buffer spring. Seemed to slow down the action, also improved recoil. Now this AR shoots everything like a champ, plus the BCG is easy to clean. Would have given 5 stars, but not sure if this BCG was either a blemish or used.

I bought this product for my lightweight 20" build. It is very well finished and lightweight, but it should really only be used with an adjustable gas block. It caused timing issues, outrunning my bolt catch and causing ejection issues because it was over gassed no matter what buffer system I used. It is very well made and a great deal. Just not right for my application.
