I have a DD V5 16" Mid length gas system, low profile gas block, Magpul MOE buttstock, Geisselle SSA-E, Vortex PST 6-24x50 SFP. I know this is not a long range gun but would like to see what it can do with better equipment. Wondering if anyone had suggestions for better buttstock for better cheekweld, length of pull adjustment, etc.? I might even change out barrels in future for better long range work. Thanks for the help.
