    AR Build - 308 help me build it

    ....it does make one wonder how many of the OEM barrel vendors that don't have the machinery/expertise to drill & rifle their tubes are using Wilson Arms blanks, especially considering that the "min" qty of an order to Wilson Arms is 100...?? ..how many times when asked the answer is "We have...

    New 6mm Advanced Rifle Cartridge

    ...just a FYI, using 30.0gn XBR8208 I was able to attain 3067 avg FPS with the Nosler 70gn VG FB, 18" 1/7 barrel, RLGS. Per my chamber, went with CBTO of 1.641", COAL of 2.121", no pressure signs on converted virgin Starline 6.5 Grendel brass. Was pressure testing, still avg'ed ~1MOA @100 yds...

    AR new barrel cycling issues

    ....just trying to contribute relevant info, it's up to you if you wish to use it. Keep in mind, an over-gassed system can also exhibit the same symptoms of an under-gassed system, i.e., the BCG out-racing the magazines feeding and activating the bolt catch speed. Good luck on your efforts.

    AR new barrel cycling issues

    ....if the AGB you are using is the "detent" type, you can save some ammo by using the procedure of (1) AGB Closed, 1 round in mag, fire, check for lock back. (2) If no lock back, adjust AGB 1 click out, 1 round in mag, fire, check for lock back. Repeat until lock back achieved. Once...

    AR15 Cycling Issues

    ...not disputing YOUR experiences with BA barrel and if it worked for you, glad you found a workable solution. ...MY experiences with multiple BA barrels in multiple calibers in lengths from 7.5" thru 20" differed. I've yet to have an under-gassed tube from them in the past 10 years I've...

    Thinking about switching to a progressive…

    ...FWIW, deprime with a universal deprimer, then tumble so you have "clean" brass running thru your dies. Decapping can be done on your old single stage press as a separate operation before wet tumbling. ...You can remove the decapper rod in your sizing die since you will be using a mandrel in...

    AR15 Cycling Issues

    ....alot of bashing of the BA barrel's in this thread, and similar in many other threads. Deserved or not?...good question.... .... a common aspect to the bashing is that the posters were doing their own builds. I personally have not seen a corresponding amount of negative posts for those...

    AR15 Cycling Issues

    ...not "trolling", but IMHO folks starting their builds with a variety of "non-standard" parts is what contributes to many of the reported issues. My personal view is start the build with "MIL standard" parts as a baseline and get thru the "break-in" period before starting to replace parts with...

    Army to buy 107,000 Sig m5 rifles, 13,000 Sig m250 LMG, total $4.7 billion contract

    ...I found the statement about the cartridge selected to be an interesting twist, what with the recent advent of the 6ARC. As was pointed out in the article, it's intended initially for "close combat forces", but also has greater lethality beyond the current 5.56's "300 meters". ....not alot...

    Brass for 77 TMK AR15

    ...although cost and time sound like your higher priority/concerns, I think availability will be the greater obstacle. 1x LC or "NATO" certified brass will handle your intended "hot loads" better and most likely achieve an acceptable accuracy that can be expected out of your stated 10.5" &...

    Least expensive AR you’d trust your life to?

    ...FWIW, if one desires some kind of list to determine parts replacement cycles, this older AAC document has relevant info that can be used to determine which "spares" to stock up on. YMMV.

    6mm ARC cycling issue

    ....barrel measurements should be used to determine gas system type, not the gas tube length (especially if incorrect tube was installed/provided). With the barrel already installed you can measure the distance from the front of the receiver to the back of the gas block or rear edge of gas...

    AR15 Cycling Issues

    ...TBH, based on my use of the household cleaner "CLR" to clean my VG6 Gamma brake on my 6ARC build (both 748 & LVR loads), I could imagine using something like a ketchup bottle with a flexible hose on it to fill the gas tube from the receiver end. A foamie ear plug shoved down the barrel...

    Mos-Tek barrels, any reviews?

    ....TBH, that was only a partial quote from their website, but it does narrow it down when one considers which barrel blank producers perform lapping of their blanks, either button or cut-rifled (or Mos-Tek" could be doing it once they receive the raw blanks....either way, it's definitely a...

    Mos-Tek barrels, any reviews?

    ...based on correspondence I had with them a few years back when searching for 6ARC barrels, they sourced blanks back then. It's easily answered by e-mailing or calling them, Maquel is VERY good at responding and answering inquiries. This is current info on their website, "The precision blanks...

    Ballistic advantage 18 inch fluted SPR barrel

    ...by "break in", I'm not proscribing the "shoot, clean, shoot" protocol, I'm saying send enough rounds down it to remove any manufacturing anomalies (burrs, rough spots, etc.) from it and "normalize" the tube. One sees many posts about BA's, both good and bad, but to be honest you see it for...
