    Fact.

    An unrelated example of that aspect is the difference between the Navy LSRB (I don't work around them any more, so I can talk smack about them, now ) and the Army's CHPM and how they deal with laser systems. I don't see how the Navy cats manage to bend, what with that stick jammed where it is......

    An excellent example of this are Navy MRC cards. If it says to use Breakfree CLP you better use it. Doesn't matter if there is something better. Since the CG also uses them we had to get an exemption from Atlantic HQ (IIRC) to use other stuff on our weapons while in the ME. We explained and displayed pics of the weapons that were being maintained with CLP and how it was not effective at protecting the weapons.

    I'll throw a chip in the pot...

    My first AR was a frankenbuild that I've since gotten rid of. Got the upper from Tony's at a Northern VA gunshow probably in late 2007. Carrier key was unstaked, extractor insert was blue. Barrel was an 11.5" heavy barrel (manufacturer unknown) with a 5.5" permanent flash hider. Initially I had a few failures to extract. I installed a BCM Extractor Spring Upgrade Kit (including the O-ring) and moved to an H buffer, and used the McFarlane one-piece gas ring (ordered from MidwayUSA). It ran flawlessly after that. During every cleaning/inspection the bolt passed the "gravity" test (bolt did not retract when stood up on workbench or extend when held vertically by the bolt lugs). At least 1000 rounds through it without issue before I traded it for an UZI a few years back.

    Last year I built a .300-221 rifle at gunsmith school, and I installed a McFarlane one-piece gas ring (ordered from Brownells) in a BCM M16 BCG. Before shooting it, it passed the gravity test just fine. I have since run exactly 100 rounds (no time to hand load anymore!!! ) through this rifle since it was built, and I robbed the BCG from it to put in a project SBR until I get a dedicated BCG for that rifle. Upon inspection, the bolt would not stay retracted when held vertically from the bolt lugs, and the BCG would drop on the extended bolt when placed on the bench. I did not measure the McFarlane ring, just tossed it in the trash and installed new standard gas rings.

    I doubt 100 rounds would have worn it out. I think I'm going to stick with standard rings, they seem to work fine and are widely available.

    To be exact M21 is Serbian, not Yugoslavian

    Did you try wz. 96 Beryl and Mini-Beryl? Those seem to work as well

    Back to topic: when I got my first AR15 some 5 years ago (Stag) I put McFarlan rings on it (those time I was swallowing everything arfcom like young pelican swallows brick). Never had problem with it and now, some 20-25K rounds later this carbine (works as rental in training/event company) works smooth with same rings set. Got them from Brownells (actually have second set somewhere in my armory, but it does not fit piston HK ).

    My personnel AR's all use them and I recommend them. YMMV.

    IG,

    He wants to know what lube you are using in the desert since you find CLP to not be working.
    My brother saw Deliverance and bought a Bow. I saw Deliverance and bought an AR-15.
