unless you've quite a lot of experience shooting, you probably will not notice any differences. DPMS has been in business for a very long time, their parts and gear are everywhere. "LR-308" or "DPMS pattern" .308 caliber AR's are one of the major industry standards that people agreed to use other than Armalite's AR-10 and a few specialty ones.


most LR-308 or DPMS compatible AR-10 lowers will accept nearly all AR-15 parts barring special ones that are modified for the longer receiver like the magazine catch. if you are doing an 80%, then machine out compatible slots or holes or whatever for the type of controls you want.
So it sounds like you're saying as long as I use a DPMS/LR style lower and milling myself, I should be gucci. Aero M5 upper should work? I have a hard time finding companies that make AR-10 uppers tbh, Aero feels safe cuz I know I can go with their enhanced version and know I will be good for the FA, the dust cover, the BCG, and everything related to the handguard. Would their be any issues with different AR-10 uppers and the DI tube alignment? Was thinking of just running a Faxon barrel at this point, think it should be fine...

Speaking from personal experience, there may be fitment issues with an aero upper and dpms lower. Aftermarket “dpms pattern” uppers fit my lower, but the two aero m5 uppers were off by a couple thou on the rear pin. May have just been stacking tolerances though, so ymmv.

interesting, I saw someone mention a dpms worked fine, but I wouldn't be surprised. Do you have recommended parts for a dpms upper, and the barrel nut (is that what it's called, the part the free-float handguard attaches to?)

Some people had the same issues with PA308 uppers when they came out. AR10s used to be commonly bought as matched upper/lower sets due to less standardization on tolerances. I know for a fact that my Aero upper/lowers have much less slop than my DPMS. 308 dust covers and charging handles are standardized as far as I know, and the FA is the same as an ar15. Same with gas tubes and gas blocks (assuming you’re using a low profile, and not an Armalite).

You mentioned faxon, and I can vouch for their 308 barrels. I’ve put a 16” mid gunner in a carbine upper and a 18” pencil rifle barrel in my hunting setup. Pleased with both, and pretty much your only options for reasonably priced lighter contoured barrels.

Handguards will almost always come with their own proprietary nut, so it’s really whatever features you want. Midwest Industries has a pretty good diagram for determining if you have a low or high profile upper before you buy a handguard. DPMS made things confusing when they called their target upper a high profile, and their standard low profile, then their standard a high profile when they came out with a lower profile upper. I have a Midwest on my carbine and A1s on my hunting rifle currently. I have also used the UTG pro, and it’s a pretty good value. Just avoid buying a wish.com free float.

this hinges on you being competent, but unlike Armalite, DPMS didn't care if people wanted to use their "specification" with Bushmaster and others opting for the "free" DPMS specification vs the licensed design that Armalite was offering. since DPMS also didn't care if people didn't license it from them, you had clone makers reverse engineer the drawings and machining instructions by measuring out finished products, leading to some variation depending on who did it.

Armalite AR-10 uppers are everywhere, but less common than DPMS (which has "high" and "low" variations). if you feel safer with Aero precision, then buy an AP upper and machine a lower to fit.

the gas tube should not vary between Armalite or DPMS, or really any pattern other than length and "type" like carbine, rifle, medium, pistol, or some of the funkier ones out there. unless you have a particular gas block that isn't standard, they should match up fine.

PSA has their own specification for their rifle and while some parts can interchange, major assemblies will not without modification.

Do you have recommended parts for a dpms upper, and the barrel nut (is that what it's called, the part the free-float handguard attaches to?)
find out what you need or want, and work with a quality vendor on acquiring those parts. the barrel nut clamps the barrel to the upper receiver using the shoulder of the barrel extension, which is threaded onto the breach of the barrel. while this is a standardized part, many handguards and some fancier accessory attachment systems may use a specific one based on their unique mounting design. unless you have a real need for something special, a typical free float tube with jam nut or a more standard heatshielded GFR handguard from an AR-15 should work fine. be aware that the handguard cap may or may not be needed, and your front sight block may have it's own particular requirements for mounting.

the complexity of a complete barreled upper receiver is why many people choose to just buy one vs assembling their own.

What are folks thoughts on handstops, angled foregtips and vertical foregrips on your regular run of the mill AR?

For me, it really depends on how long/heavy the barrel is; though I prefer wedge/doorstop types for being unobtrusive, after I got tired of vertical grips snagging & hanging up on things, along with having to modify my grip when shooting around obstacles (i.e. LBE/seatbelts & sandbags/ledges/doorframes).

Though if I'm handed something with a long or heavy barrel (especially if it's in .308 and/or has a bipod), I'd look for a vertical foregrip before the wedges & knobs, mainly because they just make it easier to tote & shift the rifle than the actual shooting part, along with being generally more comfortable to shoot from the prone.

do you need some sort of grip assistance? a vertical grip was pretty handy when i was maneuvering around small areas like an armored vehicle or buildings while on door kicking duty since it really helped to "point" my rifle at things and people, if i needed to break something with the muzzle like a window, or prod someone who was non-compliant, but it can snag if you didn't keep some awareness of it. an angled foregrip i've seen some people use to avoid the "AOW" classification on what would otherwise be a pistol, and i've had some people prefer it due to how they handle accessory interaction on their weapon like toggles, buttons, pressure pads, switches, et c. VFG's were incredibly annoying if i was shooting for accuracy and i would either remove it or move it towards the rear and use as a handstop instead when going the distance - they weren't really friendly with using a sling for that.

the only time i've seen a handstop be useful was on SMGs that would help guard the knuckle or provide a surface that would reduce the chance that you shoot your hand on something very short, often paired with a "stubby" vertical grip. the cool guy use of a hand stop to pull a rifle stock into the "pocket" of the shoulder doesn't work very well with body armor or an LBV/LBE, but some people might see it as an useful accessory in competition while minimizing protrusion from the handguard.

it really depends on how familiar you are with your weapon, how you maintain your "work space" with your weapon and gear, and if you think it'll work for you in the types of shooting you do.

even if you don't do any of that, if it helps maintain control of the weapon, keeps you and those around you safe, and builds confidence, then it's probably not a terrible thing to at least try out.

My thoughts are that in California, legally speaking there's no such thing as a vertical foregrip on a "regular run of the mill" AR; they exist only on "fixed magazine" ARs and "assault weapons." Just something to keep in mind. ;)

I wonder how many gunners in California at this point, obey those laws anymore.

I assume outside of San Francisco and Los Angeles, I expect there is a lot of non compliance.

That is the one thing that liberals hate a lot, non compliance on a massive scale.

From what I understand, no one in NorCal gives a shit about compliance.

I have mixed feelings.

IMHO a vertical foregrip, especially one close to the magwell, is more comfortable, but grabbing by the barrel is more stable.

I once had an angled foregrip, but found that it was awkward and hurt my wrist.

I have a cheapo VFG made by Mission First Tactical that attaches to a picatinny rail. I can take it on and off with a flathead screwdriver.

It all depends on what I feel like at the moment.

All it takes is one asshole cop in the lane next to you at the range. An unregistered "assault weapon" is a felony in California. A VFG or birdcage doesn't seem worth the risk IMO. Just watch your 6.

What's the story on compatibility between uppers and the various DPMS lower "generations?" Looks like there's gen 1, 2 & 3? And if the generation isn't listed in the sales listing, what generation would it be most likely to be?

Well I currently have two ARs, well one is fully compliant with the law and I gave it an angled foregrip and bipod for the lulz.

I have another AR in a disassembled state till SCOTUS knocks down the AWB.

Or Juggernaut Tactical figures out a way to make some kind of trigger that skirts the law.
 
I know that this place needs more pics so here's my hilarious bolt action thing:
