If you compare a one piece to a bow bolt, both with Micarta risers, there is a slight weight difference with the bow bolt, not a lot. Cumulatively , the bolt AND the 10x riser should yield a good difference compared to a standard whip. I have a one piece SSLR and had a bow bolt SSLR at the same time and the weight difference was not significant. Talked with Dan and the next bow on order will be a 64” Whip and 10x riser with a low wrist grip. 10x for some added weight but probably no bow bolt. Quiver full of arrows does a lot for weight too. Great choice of bow btw!
