What is a good receiver set to do an AR10 build with?

LilGucci · Jan 18, 2025

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.

I like my Gibbz.

I don't see AR10 lowers on their site. Hopefully they update it soon.

Centurion Arms 7.62 Billet Receiver Set is what I've been looking at here very recently.

2old2run · Jan 18, 2025

The Gibbz look like they are of high quality. I've been stuck on Aero for the last few builds, but their availability is sporadic at times. I'm going to keep an eye out for a Gibbz.

I would love a receiver set from JP but I don't think they sell lowers (or upper receivers) for large-frame rifles such as the LRP 07.

Yes Sir they do!!

They call it a Aemi Auto chassis system.

This is exactly what I'm looking for. I can't thank you enough! A little pricey but I'm looking for something unique. Thanks again!

Hey thanks. I'm always looking to collect receiver sets to play with in the future. I'll have a look.

I picked up a used Diamondback and will say that for the money, it is hard to beat.

Seekins SP-10 Builder's Kit - if you can find one.

The GGP billet sets seem quality:

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”.

LRRPF52 · Jan 18, 2025

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.

LRRPF52 · Jan 18, 2025

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.

I always wanted an SP10, but these receivers are hard to come by now. I'll keep an eye out, it looks incredible in that cerekote.

This actually looks really nice! I like it a lot. I'll try to find some builds that use it so I can get a better look at it.

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.

stevieb92 · Jan 21, 2025

Another vote for Mega/Zev. Assembled several using Mega Arms MATEN. Seekins is also at the top of my list but have no personal experience with their LR-308 receiver sets, just a few AR-15 sets.

tekmann2377 · Jan 21, 2025

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.

Overwatch260 · Jan 21, 2025

Just saw SLR is having an Inauguration sale on their site, includes the B30 receivers and builders sets

noobinacan · Jan 26, 2025

SLR and GGP receiver set's look great.
but they are outdone by the complete systems with handguard integration like JP and Seekin (semi-monolithic)

Mwalex · Jan 26, 2025

Check out Cross Machine Tool. I have used their receiver sets in the past and they are very well made.

I would always recommend Mega MML sets first. But GGP especially on their sales are very well worth it. Tight fit and thermal fit. It is my go to for light weight precision style builds.

B Man · Thursday at 8:05 PM

I’m pretty sure Mega is out now. Hearing that since the zev buy out they are no more. But if you can find a Mega MML set grab it! The tolerances they are made by just tickles my tism….

noobinacan · Thursday at 10:44 PM

yeah can't find them. that's large frame - yes ?

Yeah both the GGP and Mega are large frames

LilGucci · Friday at 7:20 PM

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.

LRRPF52 · Friday at 8:37 PM

Whatever is left of Mega needs to reintroduce the SF MATEN with the smaller frame.

DeathBeforeDismount · Friday at 9:34 PM

Anything monolithic or doesn't hang the handguard off the barrel nut. LMT, Seekins , mega/zev.

kenner · Sunday at 3:20 PM

I just did a build with a Wilson Combat all billet upper and lower matched set, very nice indeed, fit and finish are awesome.

What kind of MOA (fixed) do you all see out of these large frame rifles at 300 yards? Handloads?

DeathBeforeDismount · Sunday at 4:15 PM

What kind of gas milage does a car get? That's how open ended and dumb that question is.

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.

Having trouble using the site?

Not receiving emails?
