Future Build Imput

Looking to take a few basic carbine training courses in the near future.

I currently have 1 Ar built its more of a precision 18inch set up
18inch WOA Barrel
JP extended 15 inch handguard
Brake
Adj Gas system
MUR upper
Aero Lower
Gisselle trigger
ACS stock
Jp captured spring
3.5-10 Leupold.

So i need to put together 2 guns to train with 1 primary and everyone needs a back up.

first I am working on completing my SBR, ive always wanted one of the KAC 11.5 guns so i am building my own.

DPMS Lower and LPK
ALG Trigger
Magpul grip and CTR Stock
Bushmaster forged upper
Gunfighter Charging handle
Daniel Defense 11.5in Barrel
BCM BCG
KAC URX midlenght Rail
KAC Micro sight
Aimpoint Micro Red Dot Sight

this rifle is nearly complete, anything i should do different? any quality issue running the DPMS lower or LPK, kinds too late as it has a stamp or the Bushmaster Upper?

Next i want to put together an all purpose rifle,also something i can travel with if i do an out of state class and not worry about the SBR for this rifle i am eyeing building this

14.5 midlength

AXTS A-DAC Forged Lower
Palmeto Arms LPK
Magpul STR Stock w/ Vltor 5 position extension tube
ALG Trigger
BCM 14.5inch Midlength upper with pinned flash hider
Add KAC URX 3.1 Rail
Micro sights
probably get the new Vortex 1-6 optic
again this is a rifle i will primarly keep in the truck. I belong to a hunting lease so its something i can keep handy to shoot pigs or deer if needed, thus the 1-6 optic
i could always put the Aimpoint on it for an out of state training class

i am just looking to put together 3 high quality dependable and reliable rifles, i belive that between the 3 it will cover all my bases, wheter it be priare dog shooting, hunting, self defense and training

after they are done i will continue to buy lots of ammo, i would rather own 3 nice guns set up right than a safe full of lesser

so how am i looking?

should i change anything, my only regret is that i bought the lowers a few years ago before i knew much, wish i would have gotten some billet, maybe true ambi lowers, but i think what i have will run

naturally i might up grade the alg trigger later, i choose those for the price point and hopefully reliablity.

thanks for any coments.

DPMS Lower and LPK

I have used half a dozen DPMS parts kits.

There are today NO DPMS parts in any of my guns.

I am not prophesizing that you will have trouble, but others have.

Why would you SBR the DPMS lower instead of the AXTS?

The dpms was the first lower I bought 6 years ago at a local shop.

Didn’t know any better and sbr’d it 4 years ago. Been sitting ever since. Primarily a bolt guy now I done some research and want to finish my builds
