Are the lowers on ALL new manufactured lowers cast or forged? If some are cast and some forged, could you specify which ones? Saw a new one at a dealer for a good price, but he didn't seem to know which model it was exactly and I couldn't find out from your website. I it may have been ordered custom but again, I don't know. When I asked, he pointed at the receiver "223/5.56" was all it said and I got the notion that he didn't know anything. It had short round hand guards, 16"(no muzzle brake), A3 type handle and a trapdoor buttstock. Looked very nice. I believe it was a single stage trigger, but unsure. Are most new production barrels free-floated or is that an option? Any help would be greatly appreciated. I'm considering this as my first ever rifle, I'm just afraid of getting hooked.
