Well I finally gave my son the old trusty Crosman 1377, and bought my self the Crosman 2240 for $49 on sale at Bi mart. My plans are to turn it into a PowerMax-HiPAC carbine this winter. This thing is loud! So I picked up a TKO 6.5 this will help make it quiet. I have neighbors on all sides of me and I would like to shoot it more with out them hearing it.
