As I piece together my lower receiver to attach my Grendel upper to, here is what I came up with while keeping long range target shooting in mind.
Spikes Receiver (closed trigger well)
G2S Trigger
Luth-Ar Modular Stock MBA1
DPMS grip with palm shelf
2A armament takedown pins (Titanium)
CMC anti walk trigger pins
Any suggestions/reviews on my parts list would be appreciated.

MBA 1 is around $100 at Monmouth Reloading with code STOCK. $50 saved that can get you halfway towards upgrading to a JP Silent Capture Spring

Another vote for the JP Silent Capture Spring. It's not needed but makes for a nicer feeling gun when you shoot it, and it doesn't "rattle" when you carry it.

Plus, you don’t need to use the buffer retainer and spring. Which means you have extras for when they go flying across the room when you work on other lowers!

I hate to admit it, but I did that once. I think the buffer retainer is actually somewhere in the floor vent behind me as I type this.

I definitely like comfort along with practicality and something that doesn't cost what my 338 lapua did to shoot,

As mist people would around these parts i HIGHLY reccomend a LaRue MBT2 trigger. On sale they are $100 and rank up there with some of the best including the geissele's.
I also would highly reccomend the JP SCS its pretty amazing how such a innocuous piece seems to make you appreciate your work so much more.
Not to familiar with the spikes lowers but Anderson makes a closed gaurd lower as well. Its forged as well. And they are pretty dang cheap but not on quality. Just a great cheap lower. Ive seen them for sale for around $40. Check primary arms and classic fire arms. Im sure others have them for the same sale price.
I never liked paying the brand name prices when i can get similar (or sometimes better) stuff for almost half price. Sometimes you just cant help yourself and curiosity though.

My current favorite lower is the Aero M4E1. It's just well thought out, super easy to assemble and removes the slop between your upper and lower. You can pick them up for about $85 if you shop around. After that is the Areo Gen 2 which you can find for about $50, then the Anderson which you can find for about $40-$45.

Just ordered an Anderson lower, 46.13 total shipped to my ffl dealer who charges a 15$ transfer fee.

I have a matched Spikes receiver set and more Aero sets than I would want to mention on a site that may be monitored by Ed Snowdens former employers from time to time. The Spikes is a notch up from Aero - its most obvious in the smoothness inside the upper receiver. But it costs more. And who else can sell you a color filled Snowflake lower receiver if our can wait?

Jamie, the Geissele G2S come with an e shaped retaining spring clip for the hammer pin so not sure if your wanting the CMC anti walk trigger pin for piece of mind. I understand using anti walk pins on a blow back pistol caliber or rimfire AR-15. Just not an item normally seen used by forum members from my recollection. Nothing wrong with using the anti walk pin just curious if you’ve had previous problem?

Yeah those M4E1 lowers probably are the nicest. I dont have any personal experience with them. And arent the most expensive lower around. The uppers are where they truly shine. Ive had a very hard time resisting the sales at monmouth for $75 uppers on those. The lowers are pretty much just there for the ride. As long as the geometry is correct they are fairly preferential.

Upper should arrive tomorrow.

I use KNS anti-rotation pins on most of my builds. For whatever reason, I didnt use them on my 300 BO Carbine with a Timney drop in. Cant recall that LPK or if they were Timney pins, but I had the hammer pin walk right out of the Anderson receiver mid mag at the blasting range. The CMC antiwalk pins came with the CMC drop in for the 300 BO pistol I finished up a few weeks ago, and they are a pretty effective piece of mind for the price of a cheap bottle of wine.

Idk what kind of build your going for but ive always took issue with the buffer tubes on the AR platform. Its just so insanely thin. The ALG tru mil spec buffer tube is one of the very few (maybe only) forged buffer tube AND its 7075 not 6061 which is roughly twice as strong.
And then if you
really dont care about weight Vseven makes a SS buffer tube thats VERY strong. It is heavier but honestly if you have a heavy bull barrel or dmr adding weight to the rear only helps balance the peice and put the center of gravity back between your hands and grip. Especially if you add the JP SCS
Now if you dont have a heavy or dmr barrel it might be to heavy in the rear. Idk. Once i finish building mine ill throw all those together with the lighter 20" GB barrels i got and will see. It might be the best configuration. Its all up to the eye of the beholder
Can we see pics when she's done? And BTW welcome to the forum!

of course, it may take a couple weeks because optics are going to be the bane of the build.

No worries, ask around ive been squirreling away parts for over a year now. And optics are arguably the most important part of any build. I feel your pain!
