I recently purchased a LMT bolt carrier group from Quantico Arms and I noticed that the bolt was silver in color.Looks like it has been chrome plated or something. The locking lugs has some of the material like chrome or paint that had flaked off. Just want to knowing if it is indeed chrome plating and if it is normal as I have never seen a bolt like this one. If this is normal, will this bolt be as durable as a non-chromed bolt. Thanks. |

You must have bought the enhanced BCG from LMT. How much did you pay? If you paid more than $130, then it's probably the enhanced version. Chrome bolts just make cleaning the bolt a little easier. ------------------------------------------------------------- Check out the Daniel Defense GROUP BUY |
Regular LMT bolt carrier groups that you get for around $125 will NOT have a chrome bolt. The bolt and carrier should be parkerized. Current LMT bolts are deeply engraved MP and will have an O-ring on the extractor spring. |

The bolt carrier is parkerized and and has the proper staking on the gas key. The bolt itself is not marked with MP, its just a regular bolt, but with some type of grey finish on it, some type of plating. The extractor spring seems like a normal spring and has a black insert. Wonder if this is a quality bolt, and did LMT ever sell bolts like the one I recieved. I give more info later. Thanks |
I have one of those bolt I bought last year from Bravo Co., I believe that it's chrome finish. LMT made a production mistake of a batch last year and said it will not offer them again in that finish. It's a rare item and I'm saving it for my SPR build project.

Well, let's see... Dual spring extractor Sand cuts on lugs Electroless nickel finish on the bolt Radius at the lug root Lug opposite the extractor is relieved to balance lug load evenly on 6 lugs instead of on 7 lugs Carrier face has a step on it that seats against the extension instead of the whole carrier (not sure what this does) Carrier has an extra vent hole. Carrier has a re-located firing pin retainer pin.

Weren't there reliability issues with this item some time back? |
