    Hey guys,
    Looking to purchase an upper, however it does not come with a BCG. Could anyone suggest a good BCG under $200? I have read about LMT's being a good price and of quality. Also any suggestions on chrome/d parts. Longevity, cleanliness, etc. I'm not a competetive shooter or anything special. I'm just looking for a BCG that would last me years. Thanks for any suggestions/advice.

    Top quality BCG for $139.95. I wouldn't bother with chroming it, it doesn't seem likely to help much. Also, the gas key and carrier are already chrome-lined.
    Pretty much perfect as-is I think.

    Because I am cheap and not some spec-ops couch ninja, I grabbed a complete BCG from J & S gun parts at the last expo show. I think it was only $100. Gas key was staked and it has worked flawlessly for the last 200 or so rounds I have put through it. Time will tell, but with my slight firearms A.D.D. I doubt it will see more than 2k through it.

    I don't know if this helps, but the upper will be a Bushmaster XM177

    That is not a stupid question, it would be a concern on many other guns. AR-15s in particular are supposed to be self headspacing so you *probably* don't have to worry about it. Headspacing issues with ARs are very rare.

    I would get go / no-go guages juuuuust to be sure. Or bring it in to a competent gunsmith to take a look at it. They shouldn't charge more than $20-30 for the service.

    if the question is "what BCG to buy for my _______" the answer is always BCM, LMT, or DD.

    I have a nickel plated Wilson Combat BCG in my AR. It was a little pricey, but it seems like it's good quality.

    why?

    the quality of a BCG is in the steel type used, testing procedures, grain structure, subsurface treatments... all of which is invisible to the naked eye.

    There are some things you can see immediately like, does it have correct headspace, is the gas key staked properly, is the firing pin fully shrouded (standard on M16 BCGs, but not on all semi-auto only BCGs), is the extractor spring black, etc. and some things that should be mentioned in advertising like is it individually magnetic particle tested, is it shot-peened, and so on.

    i guess you got me... but that wasn't my point. my point was to express that a statement of "it looks good," tells us absolutely nothing, and that looking alone doesn't tell you it's a quality bolt.

    Yeah, it seems like it's a good quality BCG. I've put a few hundred rounds through it, including my own reloads, with no problems. It cleans up well, and the "fit & finish" is excellent.

    I am slowly setting $ aside for a fail zero setup myself. A little over the $200 you are looking for but I have heard that they are worth the money... till then I'll stick with DD.

    I was looking at the fail zero carrier for my 6.5g build. I wish they would publish more info on the secret finish. Is it snake oil?

    Get a JP LMOS
    the finish the bolts have makes them slick enough you barely have to lube them and they clean up by just wiping off the residue. Also the complete JP operating system runs smoother than any of the competitors. There is good reason that the majority of 3 gun shooters choose JP.

    Get a BCM and some Slip 2000 EWL. Spend the rest on ammo to shoot it. :thumbup: No need to spend the extra $$$ on a fail zero or other coated BCG.

    Now if you're shooting corrosive ammo, I would say it might be worth the money. But if all you're shooting is regular .223/5.56, just stick with a BCM BCG.
