I just purchased the LaRue Ultimate AR-15 Upper Kit for my second LaRue and first assembly. I need help finding a good lower. Please bring your suggestions.

Thanks!

SMOS

Be one of the first 5 to send a video of how to assemble a lower when you get your kit and you shall receive a lower-per Mark

Thanks for the advice; shopping them now.

I'll record a video of the assembly.

Mark is going to offer you guys that buy the kit a lower at some point FYI

That was my first thought. Otherwise OP should toss it on an Anderson for giggles. 

I hope so I just ordered an Upper Kit and I'd like at least 2 more LT Lowers.... 
 I may order a second upper kit in a few days.... You can never have enough...

If I do, Do I replace my aging 18" .223 Stealth (that I;ve got tons of ammo for or try the 6.5???

For us guys on the BuildAR program we were able to buy 1 lower. Don't plan on being able to buy more than 1.

Doubtful.

He said they are tracking who buy the kit. It's in the big thread. I'm not going to find it for you but it's there.

Saw that, how do you get that it means he's going to give everyone lowers?

While he didn't outright say it, a lower sale is what he implied.

I'll force him to sell me another lower by putting my 6.5g upper and MBT on an Anderson lower.

That'll learn him!

I once recall him implying.338 federal, something called a siete, a 25-08 and a Quattro...just say'en

Hey, the 25-08 was seen in the wild!

Maybe opertunity to buy lowers similar to buildAR or matching serial numbers of the past?

I'm not saying he's gonna give people one.

He's got a builder kit for sale right? It's basically the BuildAR program 2.0.

He's going to let guys that buy this kit buy a lower later on.

Try SMOS, or Noveske.

I have never understood manufacturers that offer their products incomplete. By incomplete I mean a cerakoted lower and upper receiver in a various amount of colors..... what the fuck is the customer supposed to do for a matching handguard? Then, there's the ones that will offer an upper receiver with matching handguard....what the fuck is a person supposed to do for a matching lower receiver?

Mega makes a nice ambi lower

Thanks for the feedback everyone.

I really hope Mark offers to sell a LaRue lower; I would much rather have one made by them!

Hate to have to put this on a $40 poly lower.

I have a pink poly...  ok, fingers crossed for a future sale.

My girls would love that but......   need me a texas spec lower

Sorry, pink not for sale, my fingers are crossed for a future LaRue sale - just ordered 2 uppers myself!

sounded that way, but it did not seem to be a commitment.

It may be sacrilege but I just put my tAR Upper on a Gen 3 Noveske and everything lined up perfect FYI

Im going to use the Larue lower I bought 2 years ago and has been sitting patiently waiting in the safe.

Stripper lower in purple.  Not sure what we'll do with it long term, probably Cerakote a random upper laying around to match, cuz we classy.  It was only $60, zero fks given.

Purple rain

I think this is the same that Ranier has, meaning Mega OEM's for Ranier.  The Ranier version is a little less logo-ish.

Other options for a good billet lower are SMOS (current model offers no logo, but not the same as was OEM'ed for LaRue), Tactical Innovations is another good one.

I'll be using one of my Battle Arms Development stripped lowers I have set aside for such occasions, with the hope of a LaRue lower coming along some day. BAD lowers are forged with excellent excellent features, but are rather pricey for a forged lower. But I do like them, and they give me a mil discount.

I asked the same question a few weeks ago and a lot of folks said the new GFY SMOS lowers have a changed design and do not align / fit that great.

One said the ARF lower fit great and Mega I believe.

Thanks for the heads up on the SMOS GFY lower...I didn't see the old style in stock and was considering a GFY lower in FDE to match my ultimate upper in FDE.  Guess it's back to the drawing board...

Not sure about the Megas shipping today, But I had my Stealth Upper on a Nice Mega (bought stripped) set up as a pistol while waiting for my LT Lowers to come in...
 
I had to take the upper off and put it on using Rubber mallet...  Looked and Fit Nice...  I may need to dig that guy out and use again while waiting on the next batch of LT Lowers.

Which mega did you go with, the "s" or "h" ? I was going to rock a Seekins but want to ensure that mallet level of tightness. Thanks!

Uhh, to be honest I'm not sure... 

I just picked this one up as a good dealer friend of mine at the time had a handful of nice Billet lowers in Stock and said, hey I'll let you have this one for what I got in it, till your LT lower comes in...  
So we put a LPK in it and I was off and running with it for months till the LT lower came in and the F1 came back on it...

When I get home tonight, I can try and dig it out...   I want to see what trigger I have in it anyway... 

Thinking it was a Gieslle (or how ever its spelled) two stage...  I had bought a handful of them when we started building ARs...  I don't recall using any OEM or normal LPK triggers...

Here's what I buy. might as well get the upper so you can build it into something down the road

I've had a crisis trying to pick one out the last few days. Here is my honest opinion:

1. When you go to a subforum that you will get a lot of suggestions to buy lowers from company you have never heard of. Now I have nothing against that company and it may be the mainstream "in" company for operators right now, but why chance it with such a relatively unimportant part? They may make the best lowers in the world, but I know a MEGA lower will be great, and it costs the same or perhaps less, so what advantages does xyz obscure company lower have?
2. The primary "innovation" in lowers recently has been the nylon tipped set screw that takes up the slack between the lower and upper. Nice but unnecessary.
3. Anderson is cheapest, you can "go up" in quality and pay double for a spikes forged. Everyone sells spikes. For a little less they sell stag. When you ask if you should buy a spikes or stag in a gun forum, they say buy anderson because you are paying for the name. Before you get out of the "buy anderson" territory you are at 150 bucks.
4. At 150 bucks you can get the yhm. YHM makes good stuff, imho. That said, why spend 150 bucks on a lower when you could spend 200 and get the seekins.
5. The seekins is 200 bucks now on rainier and 210 on buds. It is one of the only lowers I've found to have the trigger set screw and more importantly the pre-installed ambi release. For the 200 bucks you can save money on tools because with seekins you don't have to get idiot marks driving pins, it is all threaded.
6. Over 200 bucks you start to really pay for name or markings(see spikes billet craziness). You can find the Noveske in this price range, but it offers no apparent advantage over any other lower besides the name, and indeed the "cheaper" noveske lowers have at least one very negative review on buds for having varying widths on the trigger guard ears(iirc, this put me off, but take any single review with a grain of salt).
7. You can look into "full lowers" for the 300-500 dollar range, and pull one off there. I believe there is a blem BCM complete on buds for around 350. Problem is cost, because you are paying for parts you don't need.

I've looked all over. Jo bobs had a great deal on I believe a ruger marked lower for 80 bucks, probably a wise purchase, you get a "decent" gun name and the quality of a spikes/anderson/stag/aero/psa/ basic forged lower. However, if you are looking for a "nice" lower and want to go with a popular company that you know does shitloads of the things and isn't gonna not fit, seekins and mega billet lowers are the two I like the most(after research):

1. No negative info around, nearly universal acclaim from users
2. Not overcharging MUCH for what you get
3. Good and respected name brands in the gun community

ymmv, and if you can point me in a good direction, I might just buy your lower, but if you want to point me to the obscure, please explain why said obscure brand should be trusted over a known entity on my Larue.

Pretty sure the MEGA comes with the ambi release installed.

What is a trigger set screw?

Edit: I looked above at the stripped MEGA, I think the bolt catch pin unscrews with a hex key, you still have to install the catch and spring. Guess that's why I was remembering it as installed.

While I am waiting, here are some cool roll marks . Ar15.com. 

I just ordered a CMT billet ambi lower. Already has the ambi mag & bolt release installed and I read nothing but good things about them...we'll see.

I am just going to be patient.  Going to be a sec before I can drop mony on a scope anyway.  But after that I will just go get a lower local store if I can't get a Larue.  I really want a  Larue but can't wait forever, maybe till Christmas.  would be nice before dear season though.  Here's for hoping.

I was looking at that one or the Mega. Looking forward to your thoughts on fitment.

Anyone else know, as far as the Mega is concerned, if the Gtr-3H or Gtr-3S is a better fit?

Sorry about the late reply.

from description: trigger reset adjustment screw allows fire control tuning for optimum performance.

Apparently it takes up slack in the trigger. I believe they have upper tensioning screw, screw for trigger reset, and set screw for rear detent spring.

I doubt it would be needed for any aftermarket trigger, but it is in their marketing, so I included it.

I have a build on a Mega billet upper and lower set, so I'll be interested to see how they compare as well.
The CMT lower and Larue upper kit should both be here this week, so I should have an answer fairly soon.

My plan is to use the CMT for now and when/if Larue releases a lower, switch the CMT to my pistol build and get the Larue lower for the upper kit. Hopefully it pans out.

Interesting

Happen to get that lower in yet and see how it fits?

I did...just got it put together Fri. The fitment is great. It has the nylon tipped screw to adjust the slop between the upper and lower, but I didn't use it...they fit together perfectly.
It has a deep, rich finish that looks great and matches the Larue pretty well and the overall quality and fit/finish looks very good.
I love that it had the ambi mag release and bolt catch already installed, and both work very well. The placement of both was perfect for me.
The only negative, to speak of, is that my gen 1 pmags don't drop free...The newer ones do, as do my Lancers and my one Colt 20 rnd GI. Not a big deal as I have plenty of mags that work with it, but figured I'd mention it.
Now I just need to shoot it.
Edited, with better pics.

Ok can't wait anymore...just ordered the Mega billet GTR-3H from primary arms. At $169 I felt like it was a pretty good deal. I'll post a pic of how the upper fits with the 3H model as opposed to the 3S model.

Have to say though, as someone who's NEVER built on anything not aero ($50-$70), it was hard for me to shell out that $$ for a stripped lower.

That's still a good price for a billet lower, IMHO, and from MEGA too.  My MEGA forged lower was just over 100, for reference.

I live in Houston and picked up this lower in-store today. Started assembly this afternoon but didn't have time to finish. Will post pics when completed.

I'd be interested to hear how tightly it fits.  My forged Mega and Aero lowers require a mallet.
