I'm still in for three, just like I was before, brother.

Start at drilling them to 0.081". You might need to go up to 0.085", like I did. My numbers are with an Armalite AR-10 Carbine Gas tube, which is longer than what PSA sends these rifles out with. Fix that gas tube first.

Gas block diameters on both at .750"? 18" midlength gas on both barrels? That one I worked on was 18" midlength gas, .750 gas block diameter on the barrel, and I had to take the gas port to 0.085" to get it to run great.

Yes, and the brass is great for reloading.

M249 SAW Drums, man. 200-round belts. Mikey found me some linked blank for the can cannon - here's a whole belt.

They'll be busting it out at SHOT. I'll be all over it, for a couple Grendels here that are running A5 buffers (A5 H1 and A5 H2 in them).

I LOVE Model 52s!!! Very cool!!!

Ballistic Advantage makes good barrels. That will certainly not be a bad choice.

Right on.

Their spring is nowhere even close to the dimension of an AR-10 operating spring (Armalite part number EA1095). They can order one and compare their parts, if they want to - they'll find out how far off they are. They used to have a member here (Josiah, Jamin's brother), but he hasn't been active in a long time. Weird - you also asked how heavy their buffer was, and they answered (kinda) with the internal depth of a receiver extension- without giving a measurement. Their receiver extension should be 7 5/8" internal depth, not "kinda" or "close" but exactly - but that's not what they make. Their buffer should be 5.4oz, but it's 3.8oz. Food for thought, once again, PSA. Soak up the information, and fix your large frame ARs... if you want.

He's good - we're shooting the first or second weekend in Feb.

I've held them and fondled them, but have never shot them. I've been very, very close a few times to picking one up - interested in your review.

Damn, those things are nice!

^^^ Yep,what JT said. Those are all the part numbers. The receiver extension internal depth is important, the spring (EA1095 spring) is the heart of it - but you can use ANY AR15 Carbine H3 buffer. They're all 3.250" long and weight damn close to 5.4oz. For receiver extension options that meet the internal-depth goal, there are confirmed, verified options here: I'm not the king of the PA-10, man - I jsut got sick and tired of seeing what they were turning out, and constantly changing, for the worse. Once these guns run, they run well. When they don't run, we hear about it here, in what used to be "all the damn time..." I want them all to run, great, out of the box. Life here would calm down if that ever happened...

Not at all, will - you were allowed to air your opinion - and nobody else is allowed to air their own opinion? Doesn't work that way. You can say whatever you want, but it's trouble when someone disagrees with your opinion? Nope, not gonna happen. There are lots of "surface issues" even in finely machined metals. There are SOME additives that work, and some that don't. I witness testing of lubricants about twice a year, in person, for the last 5 years. I've seen ones that work, and I've seen that "snake oil" you refer to - the ones that don't work. I've also seen, in person, fuel additive testing. You know that Lucas fuel system treatment? You can pour it in a bowl, and you cannot light it on fire, with a propane torch... I kid you not. It will NOT burn... So, how does it clean a fuel system, then? So, there's your example disproving your thoughts on this being about a certain product or name. I can tell you this, too - there are some products that adhere to the metal, and fill in those microscopic pores, cavities, crags, crevices... and they work. Some of them work very damn well. Ever seen a $25,000 V8 crankshaft? Yes, just the crankshaft... It doesn't need any additives, and it doesn't have all those metal surface issues. That's why it's $25,000, and it takes 6~8 months to get it.

If I'm hand trickling charges, which I do quite often on a beam scale, I can get it right on most of the time. The scale just need to level, and I'm dropping in one kernel/piece of powder at a time, most of the time. It's at the grain charge I trickle to - but I don't know if it's less than 0.1 grains. If it's 0.03grains, or 0.06grains - I never see that when I'm shooting it. On a 500 yard target, it lands right beside the other one that I just shot. If it's at 845 yards - it lands less than 1 MOA away from the last one that I just shot (which would be 8.84715", in real MOA). I'll take that. It's often less than that, on the 845, which I shoot regularly, in several different calibers. i'm alright with NOT being within 0.01grains on my loads. I don't need that kind of accuracy, and I've seen the difference at distance, on what I do. It's close enough that I'm quite satisfied with the load performance at those ranges.

Storing my load data is why I'm most interested in it. It measures from 2 to 300 grains, to +/- 0.1gr (good enough for me), holds over a pound of powder, and can store 30 of my loads. I'm way down with pushing a button after loading the right powder, and it knows my load, for whatever caliber combo I programmed it for. That's WAY worth it for me. I load several calibers. 15, if I just did my die-count correctly. Several of those have numerous different loads, as well. 5.56 for example. I load 55gr range trash ammo, 69grain, and 75 grain. Once in awhile I'll load 77gr. So, there's 4 loads for 5.56. .308 Win has several loads, .338 LM has two loads, .338 Fed has two loads, 25/45 has two loads, 300BLK has three loads, .260 Rem has two loads, .300 Win Mag has two loads (working on a 3rd), etc. It's easy to see why it would be a benefit, for me. I don't care how long it takes to drop powder - as long as it drops powder pretty damn close to where I want it. If I end up going over 30 loads, and it won't store it - I have three powder measures I can set up for specific loads - 5.56 55gr, 308 Win 150gr, 300BLK 150gr. I'll get by, with that. For my precision loads, where +/- 0.1gr might not make me happy - I'll program it at 0.1gr under, and hand measure/trickle that load. Plenty accurate enough for me. I'm not trying to go out on a flat range and win a Palma Match here. I'm trying to shoot in the desert, hunt in the desert, and make sure my 2nd round is definitely on target. When it's taking 45 seconds to load my 90gr .338LM charge, I can seat the projectile, pass it through the checker, and put it in the box - then I'm ready for the next primed case to drop powder into. So, would that scale ease the pain in my life? Bet your ass it would. My $0.02... Fuk it - maybe I need to buy TWO of those scales, and REALLY ease my burden. That's some perspective to think about, yeah?...

Getting close? It's after Christmas, and been about a month. Just wondering.

Welcome, Jarhead. Let us know when you need anything.

That's fucking awesome, Kiwi!!!

Yep.

I'm just glad to see SIG get beat by a superior product for once. Looks like they couldn't buy their way into that one. LMT has made the M-203s for a long damn time. They know the industry, and they know how to make a solid product.

I think that this organization is mixing regulations to suit them. They're combining Bolt action regulations with AR regulations, until the outcome best suits what their goal or need is. Bolt actions, even as a barreled receiver group, have the serial number. The barreled receiver group could, in a controlled setup, fire a round. The stock doesn't have a serial number, and there is no "lower" on a bolt action. ARs have the lower serialized - so that's the controlled part. It can't really fire a round, unless you have all the workings of the upper receiver group attached to it - but you couldn't fire a round from just an upper, either. AR lowers are what will make a round go down range - but not by themselves. A bolt action upper that's specifically designed to mate to an AR lower - by itself, cannot fire around. You have to combine it to an AR lower receiver group, complete, in order to fire a round. I think BATFE is coming up with whatever they want, to further classify something, into something that it is not. The ACTION of this specific upper receiver is bolt-operated. On an AR platform. That doesn't fit the true definition of a "Bolt-action rifle" because it cannot fire around in that upper-only configuration. It just can't. It's NOT a "barreled action" because it does not contain or house the trigger group, in the terms of bolt-action rifles. You must mate it to an AR lower to fire a around. Same as any other AR upper. The ACTION of a standard AR upper is semi-auto operated, through direct gas impingement, or gas-piston operation. The ACTION os an AR upper is NEVER full-auto - but the lower receiver could be... That make sense? BATFE is making up their own rules,based on the wrong info. Just because a weapon is bolt-operated, does not make it a bolt-action rifle. It's NOT a "rifle" until it gets mated to a lower receiver. It's just another upper receiver. It's not semi-auto, Full-auto, doesn't fire from the open-bolt position or the closed-bolt position, nothing... Until you mate it to a lower receiver, that has a serial number (if it's not an 80% completion). Right now, those are still legal, too, those pesky 80%s. This would get wiped out in the first court trial, if the proper definitions were presented on the side of the defense. There's no other way a judge could see it differently.

BWAAAAAAAAAAHAHAHAHAHAHAHAAAAA!!!

That's why we have different gas port sizes for different gas block sizes. Notice the differences in the charts I posted in the other thread? They have two different figures, for a .625 and .750 gas blocks. That's due to the volume of that hole. It's simple engine math, really. How to calculate bore and stroke into cylinder volume. Bore x Bore x Stroke x 0.7854 = displacement, for that cylinder. Same thing with gas ports in barrels. Gotta know how thick that barrel is in order to get the "stroke" part of the calculation correct.
