I'm in the middle of a mk18 mod1 build and I can't find any solid go or no go answers on moe pistol grips and rvgs on mod1's. I was wondering if any people on ap had any good info. I know there are a lot of you out there that run block2's and othe mk18 variants.
The RVG is not an item I have ever seen in use on those rifles. There are stories and photos of grips in use from FOBUS to Hogue to Ergo, as well as Magpul. Stocks in use include CTR, VLTOR, SOPMOD.
