If you aren't quite sure about how you ultimately want your AR-15 or LR-308 build to look, or what purpose you are building it for, than our MMC Combos Upper Build Starter kits are a great place to start. We created these smaller kits with some of the essential parts needed to keep your cost down and to take any guess work out of figuring out which gas block and tube you need, or what thread pitch your muzzle device needs to be. Although we sell all these components ala carte, our combos include a combo discount to add value and convenience. You can package these together with our MMC Combos AR-15 80% Lower Build Kits you can make going from workbench to range easier than ever. We provide combos for a wide range of calibers such as .223 Wylde, 5.56 NATO,.224 Valkyrie, 300 Legend, .458 SOCOM, 12.7x42 (.50 Beowulf), .450 Bushmaster, 9mm, 7.62x39, 300 Blackout (AAC), 6.5 Creedmoor, 6.5 Gendel, 45 ACP, and .243 WIN.
