why not a M4A1 clone than? if you're going 14.5" it makes more sense no? the price difference between the DD MK18RISII and M4A1RISII is negligible.
Guess ill chime in on this thread. I am building as close of a version to this as I feel I want to afford.
Im assembling:
BCM upper
Spikes lower
Magpul STR stock
Mk18 ris II fde
14.5 DD barrel since I already have a10.5 build
Vortex flash hide
Aimpoint comp ml3
Emtan folding battlesights
Vertical foregrip yet to purchase
