Any advantage to this over standard Colt CMP marked bolt? Fill me in. Thanks.

think the enhanced version has the dual extractor springs and the differently designed lugs or something like that.

i would just get a known good bolt and call it a day

I have a LMT hardchrome bolt that only has a single spring.

Not that I needed chrome, it came that way!

LMT hard chrome regular bolts were a rare upgrade mistake from the factory.

LMT notified dealers that they will no longer make regular chromed bolts.

A lot of guys are stashing them away including me.

The enhanced LMT bolts are not affected.

Both of my LMTs have the hard chromed bolts

I have a LMT bolt, non chromed, I'm lazy and don't clean it much, but it works prefectly, top notch stuff.

I've got one of the LMT chromed bolts. I'm very pleased with it.

Thanks for all the replies. Can one of you guys that has one give me a kindergarten level answer as to why a hard chrome bolt is an "upgrade"? I'm not saying it isn't, I'm saying I don't know anything about it.

I'm not sure if it's an upgrade but I've found it makes cleaning the bolt a little easier. And since I'm lazy and I hate to clean guns I appreciate the hard chrome

OK, thanks M4arc. Easier to clean, that's an advantage. I guess carbon doesn't adhere to hard chrome as well? Any other reason why it is better than the regular bolt?

When I think of chrome I think of shiney, like a chrome bumper on an antique car or exhast pipes on a Harley. Are they shiney like that? Sorry for the dumb question but I am curious enough to go ahead and ask it.

All, each and every one of LMT bolts are MPI and high pressure tested same as Colt and MPI marked CMT bolts. Other brand X are random tested or even not at all.

The chrome is not shiney, almost flat. It's not bling-bling.

I'm putting mine away for a special project. I'll just use my regular non-chromed LMT spare bolt assy.

Thanks A-R3. I feel slightly less dumb now

Not to pick nits, but aren't the LMT bolts electroless nickel, not hard chrome?

Yep, I've found that the bolt is easier to clean, the carbon is easier to remove. That's a bonus in my book.

Decorative 'bumper' chrome and hard chrome are two very different things. Hard chrome is a very, very thin coating that will not flake off when applied correctly. Hard chrome is very hard (read durable), cannot rust or corrode and is very slick. The bore and chamber of milspec barrels and the inside of milspec bolt carriers and carrier keys are all plated with hard chrome. It is also usedd on the bores of chambers of most current military weapons from the Beretta M9 to the larger machineguns.

It can be made shiny but is normally more of a matte finish.

Only the enhanced bolt (with the double extractor springs and heavy duty extractor) are nickle plated.

The standard bolt that goes in the semi and M16 are the only ones chromed.

If some of you guys are interested you could put a WTB ads at the EE and I'm sure there are a few sellers still have some of them left.

But don't let them price gouge you.

Apparently not.
