Aftermarket Barrel/Handguard Compatibility with DPMS G-II 308 Rifle
I'm looking at putting together a .308 light precision do-everything unicorn rifle (basically do 90% of what the SR-25ACC does at under half the price by using an aftermarket SS barrel and accepting that barrel life compared to the KAC offerings is going to suck).
I'd like to run a URX3.1 handguard if possible (but building up an Aero Precision M5 receiver set into an SR25ECC knockoff would have the installed handguard alone at 40% of the cost of the rifle for me), so the DPMS G2 is an appealing prospect.
I realize that the threading is odd (unsure if it's an outright different thread pitch, different diameter, or what the deal is, all I can ascertain is that the DPMS nut is 'the' nut, and it so far only works with a few handguard options). Has anybody tried making this work, or have any other insight?
I would actually have the ability to try make (and talk my shop into making a run) of DPMS G-2 threaded KAC URX 2/3/3.1 units if that's physically possible, but I don't even know if that really is workable, let alone the fact that making a 7075 billet barrel nut isn't exactly a cost-saving move in low quantities.
Finally, would it make sense to try any of this stuff, since that platform still seems to be having minor niggles with feeding and Gen3 PMagLR's, primer and firing pin channels, and no particularly good TDP-like spec reference for gas port? I still figure the whole market is liable to change if a big player got involved significantly (DD, BCM; Noveske returning, or LMT making a Defender LR308), and if the winner is ironically enough the older AP4/Gen1/LR-308 spec then I'll have committed a ton of resources into a 7.62mm betamax. Thoughts?
