Default Choosing AR Bolt/Carrier Group (5.56/.223 & 7.62x39)

Ok, Other than a rear sight and BCG, all my AR parts are essentially ordered or in.

I need some advice on quality bolts/bolt carrier groups.

I'm shying away from M16 carriers due to BATF "interpretations" on FA parts in semis so that kills the ION Bond Bravo company BCG (http://global-tactical.com/bravocomp...utofstock.aspx) that I really want.

So I'm looking for reliability, durability, and easy cleaning. If all I need to do is add an extractor enhancement (D-fender or the like) and torque/stake the carrier key - that is not a deterrent but a chance to learn.

Please, your thoughts/experiences on:

RRA ($125 from ADCO - I'm running RRA Upper/Lower/LPK if it matters)

DPMS in Chrome ($152 on discount - http://www.midwayusa.com/eproductpag...eitemid=333375)
DPMS in TiN ($202 on discount - http://www.midwayusa.com/eproductpag...eitemid=446331)

Known Good Quality:
LMT ($130 http://www.bravocompanyusa.com/LMT-B...g-lmt-ar15.htm)

Premium:
Young National Match Chrome ($215 - http://global-tactical.com/youngnati...pcomplete.aspx)

Super Premium:
JP Stainless Tactical Carrier ($180 Carrier Only - http://www.jprifles.com/buy.php?item=JPBC-2)
JP/Leitnerwise ($159 Bolt/FPin/CamPin Only - http://www.jprifles.com/1.4.7.php#1)

Basically, I've got the DPMS Chrome and TiN on Back Order at Midway but have heard mixed things about the TiN damaging hammers, buffers,
& uppers and about consistancy w/ the chrome plating for clearance. Some seem to love them. Don't care about the eye-candy but want extra durability, cleanability and lube tolerance if possible.

Should I cancel them and drop back to a LMT or CMT - high quality, peened/inspected but "no frills", maybe later try out a JP/LW super BCG, or do any of the DPMS plating upgrades make sense?



Also on a 7.62x39 Bolt - Will the DPMS bolt run with Wolf (maybe w/ the firing pin mod) or do I NEED to go with the MGI (http://www.mgimilitary.com/store/ind...8ac2c3f975dbf1) for twice as much

Sorry for the ramble, but there are a lot of choices & factors.

The TiN parts look hella cool, but if you're going to get a tin bolt you should ge tthe tin hammer as well.

Really since you have RRA...everything. I'd get RRA.

I don't know much about ARs but from what I've read ... LMT and BCM are top notch BCGs.

But I agree with Kaos ... you have RRA everything else, might as well try the RRA BCG

No can do on the TiN hammer as I'm installing the RRA/WhiteOak 2-Stage. RRA might be be the safe bet, although I'd prefer the LMT if there is no adverse aspect in the RRA Upper reciever.

Care to explain to a newbie why there could be any adverse interactions with the RRA upper?

I'm an AR newbie too - Just lots of lurking/reading to date.

Shouldn't be any, but I understand RRA's purportedly are fairly tight fits (at least as far as lower-to-upper mating) and wondered if someone might have heard of a bad cases of conflicting large BCG vs. small receiver interference at the tolerance limits.

You're incorrect on the M16 BCG / ATF issue. Or GTS is. Whatever, the ATF issued a letter stating it is OK to use an M16 BCG in a semi-auto AR15.

Don't rule out the Young non-NM BCG. Great buy for the money IMHO.

Go with the LMT or BCM FA BCG's and never worry about it again.
