More PSA proprietary issues to throw into the mix...

I'm damn glad you got this sorted out, Rick damn glad. The part bolded above is scary, though - banks/CC companies hold us by the balls!!! As I said earlier, I can't believe this isn't bigger news yet, but it sure looks like it's going to be...

Those uppers will not work with a G2 lower. Only DPMS G2 uppers will work with DPMS G2 lowers. Period.

That is some very cool technology, right there.

Ummm, if I understand your question - the DPMS G2 upper will only work with, and fit, the DPMS G2 lower... Not completely sure what you were asking...

Very well put, my good man. I'm glad they solved this, and that the POS is locked up.

There's that archaic BATFE guidance that you can't make a pistol from a rifle. If it starts as a rifle, it can only be a rifle. However, if you start with a pistol, it can be rifle later, and convert back to pistol. Back when pistols were starting to become the rage, that was in one of their "determination letters" on a specific design (Thompson Contender, I think...). Other than that ^^^ interfering with anything, I don't know of anything else out there. Might have to check the BATFE rules and guidance on smooth-bores... *** I'm not a lawyer, and anything in this statement should not be construed as legal advice...

The DPMS Gen 2 stuff is worlds apart from the LR308 parts.

^^^ That's exactly why I said this, in that other thread:

I've searched alot for load data on this cartridge, and I've seen 3031 discussed by a several people, as well as IMR 4895. H322 and H335 both work well, based on results of others. This is all an experiment for us, thus far. The Actual load data from Sharps is pretty thin...

That was discussed in this thread - Colt and AR-15:

There's a couple places that have them - FA sells the Northern Competition NM setup, which it the top of the line. http://www.fulton-armory.com/carryhandledetachablewnortherncompetition14x14hoodednmsights.aspx Compass Lake Engineering used to sell them, but I don't see them listed on their website right now.

I did the NM A2 carry handle rear sight from RRA, 1/4 x 1/4 MOA with 0.040 aperature, and not the 1/2 x 1/2 MOA version. It's on this page: :https://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_id=280&CFID=604213399&CFTOKEN=91782427 For the front, I used the Armalite clamp-on A2 sight base with a KNS precision .040" square front sight post. Finally found the thread on that build.

NOW I get where you're coming from...

Used one on my first 308AR build - that thing is solid, and badass.

Anything from Young Manufacturing is quality. They do great parts.

I have 2 of them, man. Both are great, and love them. One is a YHM 20" 1:7 heavy cromo barrel, 5.56 NATO chamber, scoped, and that things shoot the lights out, at distance. The other is The Woody... Built this gun as a National Match iron sight rifle... RRA 20" 1:8 heavy stainless barrel, .223 Wylde chamber, National Match iron sights, and it shoots the lights out, too - for iron sights. Taken it out to 450 without issue. Need to stretch it out more, but just haven't done it. That will be coming this fall, though...

Mine is probably that heavy- or more - with the 18" barrel. Haven't weighed it yet. Lemme get to that. Answer = 8.68 pounds unloaded, 9.50 pounds with a loaded 20-round Gen 2 PMag.

They are not educated, and I bet they get parts returns, or complaints. You know, when parts don't fit. Or work right. You're whole argument SS, well, it IS the argument. Look again at what you've typed above... Just very recently, we had the whole diagnosis process of a guy with a rifle that's not performing. It's pretty obvious to us that the wrong gas tube had been used. We directly tell him - I directly told him - that he needs the real, genuine Armalite AR-10 gas tube. THE Armalite AR-10 gas tube. Guy goes to his "gunsmith" and says he needs an Armalite AR-10 gas tube. Comes back, and tells us it's the exact same length as his other one. NOT. Wrong one. WE give dimensions for said gastube. He looks it up, orders it, and it fixes the issue. He returns to his "gunsmith" and informs him of the differences, and the "gunsmith" says, "I had no idea they were different..." Bingo. Sold. That's the difference. Throw that Ford 5.0 waterpump on your SBC. It should fit, with sealant.

The (Not)Honorable Kevin DeLeon ruined us on all that...

Some of those prices are pretty decent. Scope mounts and barrels, in particular.

To get into that discussion, you'd need to understand the M-16/M4 TDP. There is no TDP on the large-frame ARs. If anything was ever close to it, it would've been the KAC SR-25 and variants.

Here's a better history on it: https://www.ammoland.com/2016/04/ar-15-rifle-historical-time-line/#axzz4g5G4WX3f Bottom line is easy - Colt trademarked the name, after the patents expired. Colt hasn't raised as much hell about the "AR-15" term use in the weapon system's designation. If they'd try it now, they'd have a very hard time going after every manufacturer, based on a term that's become common-use (that they allowed to become a common-use term). Shiit, they don't even hold the M-16 base contract with the military anymore... So, to answer your original question - yes, it's totally ok to call any piece of crap rifle you build in 5.56/.223 an AR-15.

That combo makes 800 yards pretty easy, honestly. I've been stuck with the Hornady 75gr BTHP projectiles for several years now. Very, very slight accuracy edge with those, over the Sierra 77gr BTHP Matchkings. Seriously. Cram 24.0gr of RL-15 under a Hornady 75gr in Lake City brass, and you're cooking 2750 fps. You can go higher on the powder charge, but you better test them yourself, incrementally, in very small increments, too. If your brass and chamber live through it, you can pull 2850fps with that combination of components. 2750fps is a great speed for those bullets. EDIT - ^^^ In that info above, I am NOT talking about the Hornady 75gr AMAX projectile. I' talking about the 75gr BTHP, Hornady item # 2279... You can't load that AMAX to mag length... Don't blow your shiit up...

Who currently holds the patent or trademark on the term "AR-15?"...
