marsenalHello, I am selling a Mega Arms Billet GTR-3H Ambi Lower Receiver and matching Mega Arms Billet 12" M-lok MML-420 Upper. This upper has a 12” M-lok rail. This used to be the picture perfect gucci gun build of the early 2010's and has since been long discontinued. Mega Arms (before it was taken over by Zev) produced some amazing quality firearms and the slick inky black finish has no equal. Comes with everything you see here, including the tool used to tighten the barrel nut. Asking $1,000 shipped to your FFL for transfer. Also willing to just part with the upper receiver/handguard for $700 shipped.
