I prefer the shorter slot and the round charging handle. The round one looks more comfortable even though the second design looks better aesthetically. I think an earlier answer might lead to some confusion so I'm just going to ask in another way. The VFG is simply mounted to a standard spec picatinny rail, correct? So one could change this out if they wish. Also, I'm wondering about the possibility of ordering without a barrel since I had already purchased two 3-lug barrels in preparation for a build. Either way I'm in, thanks.
