I would like to build a 6.5 grendel for my son to deer hunt with. I tried to put him behind a youth model marlin and he is just not big enough yet he is 7 but a little small for his age. A six position stock on the first setting fits him well and he is all about the military so its a win win. I am not a big AR fan ( I know I will get bashed for that comment) I know a little about them we use them at work so I am familiar just not with the caliber if some one could help me with some hand on experince it would be great I would like to know about performance with a sutible hunting bullet and felt recoil. I would like to get him one and let him hunt the special youth season here in VA but I would like to have a rifle that don't kick the crap out of him or scare him away, thanks guys
