So I have done a few ar10 builds in the past, 2 using Aero Precision m5 lowers, and 1 using an LMT lower. I have a VSeven Harbinger receiver set that I will be doing a build with later this year in October, but for right now, I want to do a new build and I want to try out a new ar10/lr308 receiver set.

What receiver sets would you recommend? I've looked at SLR, Zev/MegaMaten, NEMO, and Noveske, but I'm open to other suggestions. I wouldn't mind doing another LMT build but I'm looking to work with something new.

It would be cool to have a small frame AR-10 builder’s kit for those that want a handier rifle that doesn’t have the brick-like legacy receivers and BCG.

Something the size of the Savage MSR-10, or POF Revolution, or SFAR.

I kind of look at the SFAR as a project gun anyway, but you need their barrel extension and bolt of course.

MSR-10 is midway between an AR-15 set/BCG and AR-10, more like a Colt 901.

This is only if you have to shoot .308-based cartridges.

I think the small frame High Performance Intermediate Rifle Cartridges are eating a lot of the AR-10 market right now.

That’s what happened to me personally with 6.5 Grendel, even though I’ve been a huge AR-10 guy for so long.

My dream weapon in the 1980s was a 7.62 NATO “CAR-15”.

One thing to watch out for is making sure the BCG will articulate with the receiver set you choose, so the bottom carrier rails don’t smash into the threads and RET tower of the lower.

I think most manufacturers have that worked out now, but I think we’ve still seen collisions recently here.

Magazines and lower receivers need to have the correct height datum relative to the feed lip presentation relative to the bottom bolt lugs and bolt catch as well.

Anyone can smash parts together in a static configuration. Most AR-10 imitation companies can’t produce a reliable rifle, let alone the DIY’ers.

Gas tube heights relative to the gas tube aperture in the upper are different too, depending on what barrel and gas block journal dims you use. Some companies shoe-horned this into place without doing their due diligence in basic mechanical engineering.

The problem is that multiple companies don't want to come together to design a light-weight bullet-proof AR10 alternative that they will then license at a cheap rate (or give their patent away for free) so that we can have a standard platform for the entire industry to use. Everyone is doing their own thing with heavy-AR10's, and all the lightweight alternatives like the SFAR, Revolution, and MSR10 are doing their own thing.

We're seeing the same thing develop in the 2011 world where you have Staccato and Stealth Arms coming out with new designs that take Glock mags, Staccato coming out with their own proprietary CS mags, other companies going with Sig mags, and Wilson Combat going with their own proprietary mags, instead of all the big players coming together and determining a 9mm-focused magazine to evolve the 2011 platform towards, and away from the 45-acp mag design that became the industry standard for 9mm double-stack mags once Staccato's patent expired.

Standardization is what is needed for the heavy-AR's to be more popular then they currently are, or evolve towards a lighter fighting rifle. Working together for the greater good of the industry doesn't seem to be an interest for any of the big players. They view the pie as finite, instead of something they can grow even larger so that their share of the pie grows too.

A lot of pioneers in the SR-25/AR-10 world did their RDT&E with huge risks in the 1980s-1990s, and have continued to improve their product lines to the present if they’re even still around under the same ownership.

KAC is the only one that comes to mind that fits that mold. ArmaLite was sold to new ownership, and DPMS was absorbed by Freedom Group, went out of business after millions in RDT&E, then the name got picked up by someone else recently.

One of the main subcomponent manufacturers for ArmaLite started competing in the market with their own receiver sets (Aero Precision).

It’s cutthroat, like any other market. Some dudes will steal the corn out of your excrement before you even take a dump.

The options you’re considering should be SLR, Zev/MegaMaten, NEMO, and Noveske as they are all really solid. SLR offers excellent machining and customization options, while Zev/MegaMaten is known for precision and tight tolerances. NEMO stands out for innovation, and Noveske is always a top-tier choice for durability and quality. Other great options to consider are JP Enterprises, Seekins Precision, or Radian for premium builds. It depends on your priorities, weight, features, or aesthetics

I appreciate your input. I'm really leaning into JP, but I might also pick up a Zev or Nemo while I'm at it. Which ever one I go with, I plan on using handguards from them too. Radian doesn't make large frame rifles, not yet at least.

Lots of great options... If you wanted to spend some scratch could always do a SR-25 lower/MWS upper. Despite being different brands they mate almost 100% and look factory.

That being said I screwed together a Palmetto PA-10 and the receivers themselves were of perfectly adequate quality.

The founder of Mega has reformed a new company under the ownership (or partnership) of Killer Innovations called Icon Defense. They are starting with the AR15 platform and hopefully in the future will return to large frame AR's.

I have seen they are releasing a full mono upper like the Mega was to start with. I’m anxiously watching and waiting.

Well if you want an actual answer ask something specific. There are literally thousands of combinations of large frame gas guns out there that shoot from sub half to minute of barn. Different barrels, calibers, gas systems, frames, ect ect ect.

The fact you do not understand how stupid that question is, is why no one is going to answer you.

I’ve built 4 using Diamondback receiver sets, 13.5, 16, 20 in 308s and a 22 inch 260 Remington. All are tack drivers and as long as they continue to produce quality, Diamondbacks receiver sets will probably be all that I use in the future.

Yes and the person compelled to answer the "stupid question" with actual stupid comments that do nothing but show purported superiority to the dirty ear plebes is somehow the good guy in the mirror.

I would like to know why gun wizards like you don't just ask some specifics and get to finding out what the question really was. I guess while bored and waxing eloquent about your 100% certifiable weapon master bonafides and subsequent superiority to those around you, the idea of sharing actual knowledge is irrelevant.
