The Crosman MAR177 consists of an upper receiver and requires the shooter to provide their own lower AR to complete the gun. This allows the competitor the versatility to utilize their own high-power AR lower with a competition-grade trigger group.

Utilizing a PCP (Pre-Charged Pneumatic) power plant affords an advantage over competitors, with less recoil and eliminating the need to repeatedly pump.  “This air rifle features a multi-shot, removable, 8-shot rotary clip and an internally rifled Lothar Walther™ barrel,” according to Neumaster.  “With a fill pressure of up to 3000 psi and velocities of up to 600 feet per second (fps), the rifle boasts 10-shot groups at 10 meters of less than 9 millimeters,” he said.  The MAR177 is capable of 120 shots per fill and meets requirements for National Match Air Rifle competitions.

PCP huh? I didn’t know Crosman liked to get wet.

All I can think of is the Chappelle show skit below:

So many great lines in that skit, but the one when Dave was on PCP: “White people love Wayne Brady because he makes Bryant Gumble look like Malcolm X.” -Negrodamus

But I digress… In conclusion, the Air Rifle upper is cool.
