nerdGot in on a blem sale for the new Aero EPC (9mm /Glock mag)receiver sets, $195 with 10% off. The LRBHO is a wire linkage in the upper, pretty much the same design as the New Frontier set, and it works very well. Used a 5.25" Taccom barrel and short stroke bolt, 10oz kaw valley buffer, 308 carbine spring, radian handle/selector, Geissele GRF trigger and 9" MI SP handguard. Built it to run suppressed with a 3 lug adapter, have a 3 lug mount/extension tube coming to be able to shoot unsuppressed safely as the muzzle is about 4" shorter than the handguard. Test fired it, and really happy with the bolt/barrel/buffer setup, the Taccom barrel has a polished lower feed ramp, with a top ramp piece to keep the nose of the bullet from jamming above the chamber, and it seems to work great with HP or FMJ ammo. The bolt kit shortens the stroke to 2"(normally 3.75 in 5.56, 3" for most 9mm), and resets the hammer with less travel. Haven't used this bolt before, but after playing around for a couple mags, it GREATLY speeds up the action and has a lot less recoil and muzzle movement than a similar build with the same buffer setup, and the LRBHO still works 100%. It was a simple build, slap everything in and runs 100% with 0 need to tweak anything, compared to others I've built where the ejector usually needs a little adjustment and LRBHO linkages in the lower usually suck. I really like the Taccom setup, feels really close to the CMMG RDB system, maybe a hair sharper recoil and a little faster. Will probably get a 16" superfeed barrel in a 2nd upper to use it in PCC matches, feels that much better than the FM products build I have been using for the last few years.
