Hello All, Looking to try my hand at building out a DMR. Price Range: $200-$300 before upgrades (willing to go higher if the externals are worth it) Type: AEG Preferred Gun Models: M4/M16 or SR25 Role: DMR, sub-400 FPS (don't ask why, that's just the way it is.) Essentially, I need something with solid externals, 20 inch (508mm) barrel, and reasonably OK internals. For upgrades, I intend to limit them to a new barrel, bucking, and GATE Titan if possible. The hiccup, full length airsoft rifles seem to be something of a rarity as of late. The closest thing I've found is this: https://www.evike.com/products/28681/#pagetabs I've also encountered a few full length M16s, but those big non-removable front sights would get in the way of a scope. Thoughts?
