The SC-4 model, our biggest pure gun condo offered to date. The new SC-4 model offers a larger flip down window that folds into the side. We also made the window opening bigger to accommodate today's larger optics. For those needing more room, we have made the SC-4 model 6-inches larger than our popular SC-3 model, which translates to even more room for elbows and equipment. Dimensions: 78"H X 72" Round *Weight: 330 LBS.
