The longer bullets do much better at the longer ranges. Longer bullets = heavier bullets, being that they're constrained by diameter. If you're after the best accuracy at the 1000 yard line, the 168s and 175s are going to do better at those ranges. More importantly though - what's the twist rate on your barrel?

Mike, my brother... That's why I like to shoot with YOU. <thumbsup> :banana: I want to keep this thing 5.56. Modern, free-floated version of the Woody.

I need the thing to be impervious to ALOT of $hit. When I'm usually wearing a cam, it's doing something that can cause me some pretty serious bodily harm. Not shooting, typically. $hit with internal combustion engines. I wish I had one on lat T-Day, when the Big CR threw me on the ground. I had one on when I had the LT-R 450 race quad on the supermoto track - and I high-sided that biotch. THAT was FUNNY! I'll try to find that vid someplace... <lmao>

What about BLOOD? I need one that's impervious to blood... I'm just sayin'... <dontknow>

Love those grips - Awesome!

Under $16 for the Gen 3 10-round LR Pmags from DSG Arms, if you have a MIL/LEO account with them. Under $16 for the Gen 3 LR20s, too. <thumbsup>

There's so much power in the size of the .308 Win cartridge - running rifle gas on a 16" barrel on a .308 AR isn't going to affect cycling one bit, provided it's a quality barrel from a manufacturer that knows what to build. You could probably take the barrel shorter than that, with rifle gas, and it would run. EDIT - Some things are shocking... check this out. Read this article: http://www.thefirearmblog.com/blog/2011/08/13/ar-15-hacksaw-pug-15/ When this all went down, there were SO many people giving this guy $hit, saying it wouldn't run, etc. It ran. Holy Sweet Jesus, it ran. Here's the original thread: http://www.ar15.com/forums/t_3_118/543391_Introducing_the_andamp_quot_PUGandamp_quot_.html

When choosing a Geissele, read the reference charts first - figure out what you need/want in a trigger, then match that with what they offer in their reference charts. Believe me, they make something that will suit your needs/wants. Next - SSA over SSA-E. They're identical in function. Identical. Same trigger, really. The SSA has a combined pull weight of 4.5 lbs. The SSA-E has a combined pull weight of 3.5 lbs. Doesn't sound like much, but it's a HUGE performance difference. I would recommend the SSA-E every single time, over the SSA. The extra $$$ in the price is worth it. Next, again - if it's a Geissele trig, and it has a "D" in the acronym, that just means it has a straight trigger, not a curved one. For every single Geissele out there that has a curved trigger, there's a version that has a "D" in it with a straight trigger (not counting the new, weird specialty trigs for the SCAR, etc...). Match up the operations and weights of the triggers, and you can see the curved trigger version and it's straight "D" brother.

Went after a gas-operated 9mm AR like that. Can't remember the manufacturer, but it was high end stuff - it just wouldn't run worth a damn. Swapped the H3 buffer for a standard carbine buffer, and it still wouldn't run worth $hit. Went immediately after the gas port. I can't exactly remember what it was, but it was around 0.060". Went up once, and it ran most of the time. Went up again, I think to 0.083", and it ran like a Singer sewing machine. With the H3 buffer. Shortly after that episode, I started measuring and recording all the gas port sizes on everything I built. If there were ever any problems down the road, I had that info to refer to.

^^^ Those things have been out for years now, at least in prototype form. General Rule: If it's a combination vehicle, it can't do any single thing well. If that biotch was solar powered, it would make a hell of a survival vehicle, though. <thumbsup>

He might be skeered... <dontknow> :banana:

I KNEW it wouldn't take long to be seen, but you were on that one in THREE MINUTES!!! <laughs> <lmao>

I'm REALLY itching to run that Rainier UltraMatch barrel, and see what it does. I looked at the WOA barrel already (beautiful), but didn't think to look at Compass Lake. Gonna go see what they have now... By the way, they have THE BEST free-float setup for a National Match A2 build - that one trumps all others in strength - smart design with the modded gas tube. <thumbsup> <thumbsup>

Should have a matched stripped upper and lower, plus a barrel, on the way in a few days. <thumbsup>

That's all the 308 ARs, brother, not just Armalite. It gets confusing building one, with the three major patterns out there. I feel REALLY bad for all those RRA guys, though... <lmao>

Good modification, man - awesome work. <thumbsup>

Welcome aboard, man, another from AZ - make no mistake about AZ, though... It's been cold here, too. Have to put on a sweatshirt or light jacket recently, which just sucks! <lmao>

Nice lookin' rig, brother! <thumbsup>

Brother, I'd love to have that 4-monocular setup. The damn thing is SIXTY GRAND!!! Yep, $60,000. That's SIXTY THOUSAND DOLL-HAIRS!!! :eek:

Been kicking around the idea of building a version of a Squad Designated Marksman Rifle, the SDM-R. I'd stay very true to the design, and just change a few things that I like to run. This long little bastard could get very expensive, very quickly, so that leaves me up in the air on it. I've already got a badass 20" 5.56 precision rifle, the YHM upper, lower and 1:7 heavy barrel - one of the most accurate 5.56 rifles I have. Then there's the Woody, 20" .223 Wylde rifle. Love that thing. Then the Mk12. 'Nuff said on that. I'm just feeling the need for a SDM-R, for some reason. Changes I'd make would include the Rainier Arms UltraMatch SDM-R barrel, DD Lite 12.0 rail, and a few other things, but it would be damn close. I'd paint the $hit out of it, too, but tastefully. Barrel: What say you? Toss some input in here and let me know.

GS, in relation to bolt travel, and how much of a gap you should have between the bolt face and bolt stop - there's no set in stone dimension for that, but there are some practical answers/info on it. Take a look at the blowback-operated pistol calibers, when running through the AR platform - there are special, longer buffers out there to limit the bcg/bolt travel. Blowbacks have so much bolt travel that they'll break bolt stops - too much over travel. That's the reason for the longer buffers - limit bcg travel in order to prevent broken parts. In a nutshell - the less overtravel you have, the easier it is on parts. As long as it travels enough to lock the bolt back. The more overtravel, the harder it's gonna be on parts. Doesn't necessarily mean you'll start snapping parts, but the parts in your rifle will suffer from fatigue or breakage long before an identical rifle with less bolt travel - this "assumes" that both rifles function fine, too. P.S. On a blowback pistol cal AR, if you don't run the special longer buffers, stack $1.75 in quarters inside the back of the receiver extension before you put the spring in there. That stacked thickness is the equivalent distance of overtravel that the pistol cal blowbacks have.

Hadn't heard of that until you mentioned it - good info. Like we can even FIND some M22, though - man, I haven't seen that stuff on the shelves since last Jan. I wish I could find it, but when I do I'll be looking for those lots and stay away. <thumbsup> Here's the Winchester info on it, for others: http://www.winchester.com/library/news/Pages/s22lrt-recall.aspx

Internal depth on the receiver extension should be 7", unless it's an Armalite AR-10 carbine receiver extension. The AR-15 stuff is all 7" internal depth. Get another receiver extension, brother. That one's too short. <thumbsup>

^^^ Full-length size it, in the case of those?

I'd be curious to see the chamber condition of the rifle that stuff was shot out of. Too much headspace. Case head separation, looks like.
