    Dano,
    Many shooters have chosen to send a quality carrier to Robar to get coated with NP3.
    Personally I personally use LMT/CMT/Colt parts. I'm debating getting my LMT carrier done in NP3 because it came pretty rough around the edges.

    http://www.robarguns.com/np3.htm

    You can also type in "NP3" in the search blank on the homepage of m4c and it will give you a list of all threads pertaining to NP3 (find out what others say).

    Hope this can help,
    Dave

    +1 on NP3'ing a BCG. Robar did my Bushy BCG and it cycles slick as sh!t. Very easy to clean, too.

    As far as the Young BCG, I have also heard good things about them. I plan on using one in my present CMMG middy build. Rainier Arms sells them, so they must be good.

    As far as round counts, I doubt it will last much longer than a BCG not coated with NP3. NP3 is a teflon based coating and I doubt has any affect on the punishment a BCG takes. I would still replace it a the "suggested interval".

    It will probably make your weapon more reliable under circumstances when you are firing a thousand rounds at a time and are unable to re oil/lube the moving parts.

    It's a toss up for me; I can't afford to shoot 500 rounds every range trip. Right now I can only afford to shoot 500 rds a month. So for me, NP3 wouldn't make any sense, I would rather spend the $130 on another MPI BCG; IMHO.

    If you have the money- Try it and be sure to tell us your opinion on it.

    The bolt carrier in my M4A1/Recce here is a Chrome one - cleans up slicker than snot - and runs really smoothly in the rifle.

    The carrier has more than 17k rounds thru it and still going strong -- bolt is a Colt that was had fitted to the douglas barrel when it was built.


    I'm looking at getting a new shorty here -- and when back on leave may looking into getting one NP3's as the coatings look pretty good.


    I had a semi auto Young NM bolt carrier - worked in a 20" gun but did not work in the 11.5 - I sold it shortly after so no real results.

    Kevin,
    Is the bolt chromed also?

    Sounds like these are out of original USAF M16's from back in the mid-60's. These rifles had no forward assist capability.

    I saw some of these no-notch/chromed bolt carriers still being used in active duty USAF rifles up through the mid-70's, but most had been replaced with notched/parkerized A1 units.

    I used to like the hard chromed BCG's, until I found that they sometimes don't work well with Billet upper receiver (LT and VLTOR). I have switched the JP Ent. Tactical bolt carrier.
