I happen to have one, and purchased it because it was compact and because it came with a peep sight. We cannot use optics during the muzzle loader season here. Coincidentally i happened to shoot it yesterday for the first time since May or early June; not sure. Left it loaded with 105g of BH209 and a 300g SST with a low drag sabot since then. Some feller was sighting in his gun and shooting across the road where i normally shoot, so i drove on by, and found a place where i could shoot about 70 yard according to the range finder. Set up a target, and inserted a primer, and shot from the cabin of the truck. The charge went off as i hoped it would, and i loaded and fired two more times, and loaded again and came home. Season starts here December 13th, and am looking forward to packing the compact, accurate X7 around, and hopefully will get some does for the freezer.
