    Does ANYONE have a source for this rail?

    CMT makes nice stuff & I really like their receivers, but that rail is like lots of others. Look at the Ion Lite series from SLR..............their rails are some of the very best & some of the best looking rails available. SLR Ion Lite 13.7" MM

    Criterion barrel brass pressure signs

    I've spent half a lifetime working with electroplated chromium & other types of coatings as well...........just not on gun barrels. And that's a schitty chrome job; the underlying chrome in the areas shown was plated as abnormally nodular/rough. And the beginnings of the chrome peeling is...

    Riflespeed or Superlative for running suppressed?

    Not sure what new products you are referring to with SLR, but their AGB is my preferred device. It works very well, fits about any HG as the SLR's are some of the smallest ID diameter available, & it is easy to take apart & clean if necessary. Only real downside, if anyone really views it as...

    Bolt carrier for precision AR-15

    Young's website is back up & running. Not sure who is running the business now though. MM

    Centurion cmr vs geissele mk 14/16

    Those a 2 of my favorite as well, with a slight nod to the Geiselle because of the longer barrel nut & ease of taking it off if needed. But, IMO, the best of them all is the SLR Ion Lite. It has a barrel nut about the same length as the Geiselle with a better finish. All 3 are about the same...

    New Purchase?

    That would be a great option, if not going with a 5.56. Problem is, of course, a big WHEN? KAC doesn't move very fast. Despite the Fanbois on one end & the Haters on the other end, I don't find much not to like about KAC's small frame rifles except the cost. MM

    New Purchase?

    Hmmm, didn't know that; it still shows on their website. When did they stop offering it? MM

    Charging handle toss up

    Geiselle, the best IMHO. MM

    New Purchase?

    Since you seem to like KAC, why not an SR-15, MOD 2, LPR? It has a somewhat lighter contour Kreiger barrel than the MOD 1, but I've never seen a full evaluation of the MOD 2. I have a MOD 1 with the slighter heavier Kreiger barrel & the UXR 3.1 handguard; the MOD 2 also has an M-LOK handguard...

    LaRue MTB 2S vs Geissele SD-C

    I have several G's, all SSA, SSA-E & G2S's; I also have several Larue's & several single stage triggers. Between the Larue & the G, SSA-E, right out of the box, the G is noticeably better in that it's lighter. But if you want to change the springs on the Larue, & maybe stone the sear & hammer...

    Precision AR -15 10 shot moa groups

    Before you do anything else, I'd suggest getting some Sierra 69 & 77 gr. SMK bullet as they are a know commodity so far as generally being accurate bullets. And the concentrate on the trigger control shooting from bags. If all that fails, then you're into new parts/assembly technique. YMMV MM

    73gr ELD M and CFE 223

    CFE-223 is a piss poor sub for 8208. While the CFE is OK for general loads, I have not gotten best accuracy, compared to several other more favorite powders, with several different bullets. MM

    Most rigid handguard/upper

    Well, I don't know who's AGB you're trying to fit under those rails, but SLR's (& plenty of other) AGB's will fir under those rails all day long...................I have several SLR rails with no issues at all & well as Geiselle rails, which are even smaller, again with no issue. As for stiff...

    gas block roll pin

    Use a punch to align the tube & the gas block holes, & use a piece of masking tape to hold them together. Place the gas block into a small v-block & use a roll pin starter punch to get the pin started. Finish with a standard punch, pliers or vise as you prefer. The taping of the tube & GB does...

    Wilson combat vs White Oak Armory

    I have 3 WOA barrels, all 18" SPR version, & all shoot very well, 10 shots right at MOA or slightly less, clean well & are not finicky. I have 2 WC barrels, both 16", one is a lightweight @27 oz, the other is a very lightweight at 21 oz. Both shoot 5 shots easily into MOA & are far better than...

    What AR15 cartridge is a worthwhile step up from 5.56?

    I'm invested in the 5.56 in the AR platform, for for all practical needs, at reasonable sane ranges, MK-262 is sufficient. But if I wanted to step up performance, in spite of some of the issues, I'd go with the 224 Valk slinging 88's as that is a substantial step up from the 77's at 2750'ish...

    Headspacing on 2 different AR barrels: need some input:

    Actually, I wouldn't want it either, because I really don't want new factory brass to stretch that much either. But BC says he doesn't shoot factory ammo so it's his call. A local smith would have to do LOTS of AR barrels before I'd use one. Besides just the actual chambering, getting good...

    Headspacing on 2 different AR barrels: need some input:

    Sounded like CLE set the HS to zero. Not wrong for a precision gun, but tighter than you would normally get from separately bought components. And your smith fitted the other one to a dimension near max. Worst combo you could have gotten.........one long, one short. Who'd a thunk it? LOL MM

    Headspacing on 2 different AR barrels: need some input:

    Next time you order a barrel from a custom source, just send the bolt you plan to use & tell them how much HS above zero that you want. Or buy a bolt from them. Most commercially produced barrel/extensions/chambers & bolts will end up at +.002-.004" HS when assembled together. You have 2...

    Headspacing on 2 different AR barrels: need some input:

    Leave the CLE barrel alone; you are at minimum HS...................not exactly ideal in a semi-auto, but most factory ammo is below that number & if you get some a thou or 2 over that, it will crush fit. Since you are now only 2.5 thou different, so size to the larger chamber plus .001" & you...
