Things I liked:This new Crosman MK-177 Tactical Air Rifle shoots as accurately as my Crosman 2100 that I have owned for over ten years. I believe Crosman put the internal components of the 2100 into this pellet rifle. Anyway, the MK-177 shoots accurately over and over again at twenty yards with four pumps, thirty yards with six pumps and fifty yards with a full ten pumps.
Things I would have changed:From the picture of the MK-177, you can clearly see that it needs a riser to mount a scope or other optical device. I purchased an AR-15 detachable carry handle with a picatinny/weaver rail mount. That worked perfect for a red dot sight. Also, The Crosman MK-177 has a fake ammo magazine that hangs down and gets in the way when cocking and shooting. I took a hack saw and cut it off. I thought at first that there would be an open void, but to my amazement and delight, there is a cover plate. I just sanded it down a little bit and it looks original.
What others should know:At the same time you purchase the Crosman MK-177, also include several 4-packs of Crosman pellet magazines, a box of 1250 Crosman Wadcutter pellets, an AR-15 carry handle with a weaver/picatinny rail for mounting optics and a red dot sight. After that, you will spend hours enjoying how well this new 2013 Crosman MK-177 performs. It's fairly easy to cock and amazingly accurate. I highly recommend it.
