Yea thanks BOS. I could probably use a 2" barrel for the shortest wgp ever! More like an 8" for a bit of accuracy. Really tempted to use the ccm pump as fore grip. I just have too many Ideas for a fore grip to figure it out right now. I think I want it at an angle and fairly short. And I found some metal for a thumb lever but it's going to take a bit to cut out. And i have barely started figuring out how it will fit with out creating any negligent pinch points. The lever hasn't pinched me yet and seems unlikely too but the back block got my arm once when I tried spinning it.
