I have over the last 25 years of building , repairing and shooting large frame AR's come to the conclusion that if you can't afford a baseline gun like the SP10, then you can't afford a large frame AR.
LMT, JP, Seekins, KAC, HK , (add Geisselle to the list) and a few others are the only ones worth owning. They will work.
I have owned the above in addition to DPMS, S&W, RRA, POF, LWRI, PSA, CMMG, Aero and a few others that were either trashed or sold to some idiot for pennies on the dollar. I have the tools , knowledge and skills to build them from the ground up, but i refuse to use cheap parts, and when I can, try to order all the major components from the same manufacture to ensure compatibility and avoid tolerance stacking issues. I don't even like building large frames anymore. There are just too many places issues can and will creep up and its not worth the time and money to run them down.
Seriously dude, just buy an SP10 and be done with it. If you can't afford that, then save up. Anything less you are really just buying shit you cant trust and most likely will loose a bunch of money when it comes time to dump it for what you should have bought in the first place.
And with all that being said, the large frame AR is almost obsolete today with cartridges like the 6 arc. You get 90% of the performance for half the cost, less weight, less recoil, way easier to shoot and with the small frame, have much more options to build something that will work vs the large frame. Unless you need the downrange energy, its just wasted on steel or paper and arguably humans when you look at a hit causing a casualty either way. A hit with a 6mm is better than a miss with a 6.5 or .30 cal bullet.
