I think that is exactly what survivalshop means to accomplish with his 16" vs 20" testing.

Not really a "pic," but pretty damned funny! <lmao>

Thicker base, from what that last thing I found was... Some chopping is about to happen.

Found a reference for the difference - and I still ant to cut some up. If a firearms is chambered to the 7.62 NATO spec, it is likely to be unsafe to fire .308 Winchester for the same reasons that it would be unsafe to shoot a rifle that it could swallow a field reject gauge with room to rattle: Excessive headspace allows cartridge brass to flow too far forward under pressure, potentially stretching at the web to the point that the case ruptures, causing an explosion. 7.62x51mm chambers get away with being so loose because 7.62 ammo is made thicker at the base than .308. The extra brass provides enough material to prevent ruptures, and is the reason why most reloading manuals advise downloading by about 10% when using military brass. Conversely, thinner .308 brass provides more case room, but less leeway in chamber dimensions. Good read: http://how-i-did-it.org/762vs308/chamber.html

In light of that data, I think I'll go cut up some 308 Win and 7.62x51 and measure some stuff out, just to see what's going on with the brass. Doesn't make too much sense to lower the powder amount in NATO brass, on this caliber, considering the fact that .308 Win has higher chamber pressures over 7.62x51. Don't know then... <dontknow>

Bah - just trying to "pay my rent." Drew charges me a fortune just to log on here, and the more I post, the more he lowers my rent... <lmao>

You have an Armalite AR-10 carbine receiver extension, then...

The difference is in the 5.56 NATO vs .223 Rem stuff - not in .308 Win vs 7.62x51 NATO.

These two guys in the red circle here - easy to confuse:

Yep, disregard. G triggers have their own parts already... How'd you put this all together? Not a complete lower parts kit? Stripped down lower parts kit, minus trigger, then the G trigger? Or, all small parts for a LPK ordered separately. Even if you don't have a disco spring somewhere, you might have been sent one by accident, instead of the correct spring... Just thinking out loud here, trying to figure out what's going on. From what that vid shows, it's the only logical solution to what's going on here...

If Sprinco is making a 308 AR buffer spring now, you can guarantee it's a good one, and a very worthy replacement part. <thumbsup>

Check your trigger - if you have a straight spring in that trigger, for the disconnector, then the disco spring has gone somewhere...

You didn't, by chance, use the disconnector spring in there by accident? They're very similar, but the disco spring has one flared coil at the end of it, to keep it wedged in the bottom of the trigger. A disco spring, inserted with that flared coil outboard, then the detent inserted into that flared coil - would wedge itself down in the hole... Thus, compressed, stuck spring in there providing no spring pressure.

Zero spring power, returning it? Was that gravity dropping it back down?

Good update, man - nice seeing the differences here in this rifle. That's a 2-stage trigger - you'll see that hammer profile, or something similar to that, on most 2-stage triggers, regardless of manufacturer. That's the way a 2-stage trig looks. Moving weights inside the buffer is the way it's supposed to be. Stops or lessens bolt bounce when the BCG slams forward. Normal.

With Seekins Precision doing a 308 billet set now, it'll only be a matter of time before they do their enhanced bolt catch for the 308 rifles. Here's the 5.56 version:

I know you guys hear me raving about the Geissele triggers all the time, plus a few others. One I talk about every chance I get is the Armalite 2-Stage National Match trigger (P/N 10309050). Full retail on the trigger is $145, but you can find it a few dollars cheaper from some online vendors, when you look. Without money as a consideration, I will always look at a Geissele trigger first. No matter what your intention (intended use) is for a trigger, Geissele makes what you're looking for, and the trigger will always perform exactly as they say it will. You will also have unrivaled customer support if there is something that you don't like about your G trigger - just call them up. Now, in reality, money IS a consideration. More often than not, it has to be THE consideration. The pricing for this Armalite trigger is pretty good, and the trigger is more than pretty good - it's a damn great trigger. Before anyone gets started on "every other company's National Match trigger," let me just say something - this one isn't the same as a CMMG, RRA, other... The quality of it is much better, and it's got some pretty simple adjustment features built in. Outside of the internet stories of RRA NM triggers going soft, I've never personally shot one - for the reason of those very stories. However, right here on this site, we heard an account recently of an RRA going soft and losing it's second stage... Food for thought... This up there ^^^ is the main feature for the adjustability function in this trigger set. See those three tabs on the sides of the disconnector? The disconnector has an additional spring that fits into those tabs, and each tab UP that you go is appriximately a 1 lb reduction in trigger pull weight. So, in a nutshell, from the bottom position you can adjust UP to a 2 lb reduction. By adjusting that spring position, you adjust the tension (or "drag") that the disconnector has on the hammer, thus changing the trigger pull weight... There's an Armalite Tech Note that further describes an additional adjustment process, to further reduce pull weight beyond that top spring setting. I performed this immediately after installing this trigger (made the max reduction in pull weight, with the additional step in the Tech Note), and I can tell you that it works, very, very well. The trigger started out in my Mk12 Mod 0 build: Ultimately, the trigger that was destined for that rifle was the Geissele Hi-Speed DMR trigger, so the Armalite NM trigger came out. The Armalite trigger will now and forever live in the 300 BLK rifle. I will never replace it with anything else, in that rifle. Here's the Armalite Tech Note (Tech Note 68) in the additional adjustment that you can make - it's titled for the 2-Stage Tactical Trigger, but further down in the doc is states it's for both trigger setups, with the National Match Trigger included for the Tech Note: http://www.armalite.com/images/Tech%20Notes%5CTech%20Note%2068,%20Tuning%20the%20ArmaLite%20Tactical%20Two%20Stage%20Trigger.pdf

I've got so damn many of the first gen mags... <lmao> I'm waiting for the Lancer L7s to hit the streets.

You'll freak when I tell you the MIL/LEO price on those - less than $16 each.

Or stick an Armalite bolt in the bolt carrier.

That was fast, man - I'm impressed. You posted this thread on the 14th, sold your rifle on the 22nd and order this then, and received it already. Good stuff. <thumbsup>

Dude, is that your stick?!... Sweet looking rifle!

^^^ Hell yeah - I had to check Mike out pretty closely after the shoot with Greg and Rob a few years ago. Had to see if he was smuggling Kimbers in his pockets... :eek: <laughs> We can definitely pull one of the SSA-E triggers out and put in that boomstick - you'll like that one. <thumbsup>

HAHA! Decisions: #1. Decide to sell beater rifle. #2. Hit the reloading bench. #3. Realize that you have some prepped 5.56 brass sitting around - load it! #4. Realize that you got rid of the rifle that shoots that ammo... Hmmm... #5. Decide to buy beater rifle... <lmao> I love it, man, love it.
