Everyone, it's yet another gun recommendation ask.
This time it's the AR-10 platform. All I know at this time is that there are 2-3 broad "patterns" to choose from and they aren't exactly compatible with each other.
Afaik the PSA AR-10 Gen 3 is one "pattern" and something like the Aero M5 is another "pattern". I know the SIG 716i is a DI AR-10 with a few proprietary SIG parts.
Beyond that, I'm at a loss. To be honest I'd be OK with a PSA AR-10 for general semi auto .308 work all day but I'm wondering if any other maker has something "better" for similar or slightly more money.
Thoughts, suggestions, or should I just go get a new built FN FAL with a Picatinney rail on top and some M-lok furniture? Thanks
I just finished an Aero M5 myself and here's my parts list:
Aero M5 lower ($149.75 including tax&NICS)
Aero M5 upper ($138.07)
Aero .308 carbine buffer kit ($53.09)
Radian Raptor LT charging handle ($90.55)
Brownells .308 Nitride BCG ($149.99)
Ballistic Advantage 16" Government Profile Mid Length ($101.67)
Surefire Procomp Muzzle Break ($89)
Areo M5 LPK w/ FCG ($75.24)
Expo Arms Mid Length Gas Tube ($8.95)
Superlative Arms Bleed Off Adjustable Gas Block Clamp On ($89.99)
AimSports DPMS High 13.5" handguard ($54.59)
Trijicon Credo 2.5-10x56mm ($519.99)
Burris AR-PEPR 30mm mount ($88.36)
Magpul Fixed Carbine Stock & MOE Grip ($30 bought used)
There's really only two patterns: DPMS which is the most affordable for .308 AR's and SR pattern which means Serious Regrets because it's expensive. The best budget option for your build would be Aero M5 which means you would need to go with the DPMS spec, Aero specifically uses DPMS high and it is very easy to locate affordable parts (sales etc) I would stay away from PSA and the Sig 716, but that's just me. The most important thing you need is the adjustable gas block and a proper buffer system for your build because AR-10's are very picky regarding those. The only thing you can interchange between SR and DPMS spec is the buffer system.
I do recommend getting the gas block I used because it's bleedoff.
Edit: If you go with the Aero M5 upper and lower, GET THE AERO LPK, you will need the Aero takedown and pivot pins for the M5 because they are longer than other makes of pins, so ensure a proper fit when assembling.
