AR Thread

[gimp]

what if he's got a middy (he probably doesn't and still do it)

[res]

From posts he has put up we know he doesn't.
But good point for others reading.

So for them, and not the wonderfully pedantic (to me this is a compliment) gimp

Basically both a 20" and 14.5" mil spec ar have 7" of dwell time (barrel past the gas port) as this is what the so called experts feel is needed for a super reliable AR in the hands of your average solder(read as potential muppet) during heavy field use.
In the real world of the NZ ar user less is just fine, especially if the ar has a suppresser on as this ups the back pressure and arguably adds slightly to the dwell time-smarter people than me can argue about this, I just know from experience that
A 16" cut to 14.5" will work just fine, hell, cut it to 12.5 with a can and he will most likely be fine without even having to change gas port size.

Ok someone help me decide please, I'm torn between a 12.37 inch (314mm) keymod evolution or a 11 inch (280mm) non keymod evolution that comes with 3 rails. Thinking I'll shorten barrel 1.5 inches to land the bushing.

12.37

[anderset20]

Keymod 12.37 is $60 more and comes with no rails. 11 inch standard comes with 3. Still 12.37?

Standard 12.37?

[anderset20]

Just a case of what's in stock and what's not, it's just the toss up on keymod? Is it that much better?

So I used those Brownell mags on Sunday and FUCK ME did you curse them or WHAT!? I could only get 60 or so rounds down range before I couldn't be fucked dealing with all the failure to feeds / misfeeds.
Do NOT recommend those mags at all.

That bugger moment when your new suppressor bushing ends up right in the small section of barrel

FYI, the new SileNZ carbine or subsonic suppressors will fit an M4 profile barrel and locate the rear bushing to contact just on the front edge of that step down on the barrel. Good hybrid alloy units, and provided you arent doint mag dumps they will give good service. (Like any alloy suppressor you have to take care not to over-cook them.) Available from GunsNZ.com or me. Gunsnz have them with bushings all ready to go for the stag arms AR barrels. Cheers.

So you are the 3rd or 4th (5th?) person to say they are crap.

So my 4 teflon coated 6/14 dated ones didnt work at all. Brownels sent me 4 non-tefloned mags dated 1/14 as a free replacement but I have not tested them yet. Anyway I just bought another two 5 rnd stag mags off gunsnz.com hopefully they will be as flawless (250+ rounds no issues) as the one that came with the gun. I need at least 1 more for WSRA but I am spent out for march having bought all the bits ($200) to reload 223!
