The Crosman A4-P Full Auto is a fun and exciting tactical CO2 BB pistol designed around the AR platform, so you can get the same can blasting experience of an AR type air rifle, but in a more maneuverable size. With both semi auto and full auto operation and reaching speeds of up to 400 fps, this airgun will give you hours of enjoyment when plinking in the backyard.

This airgun lets you have the feeling of real steel AR style operation, with realistic weight and functions, plus blowback action to simulate recoil. With a 25 round drop free magazine that holds two 12 gram CO2 cartridges and BBs, you can get something that works a lot like a firearm without wasting a bunch of money on ammo or worrying about excessive noise.

The realism of this airgun continues with an AR compatible textured pistol grip for additional comfort and a firm hold, plus a removable textured sleeve covering an AR compatible buffer tube. You can swap or modify either of these items to customize the gun to suit your preferences.

For optics options, this air pistol includes an extended top Picatinny scope rail with a removable red dot sight, plus three additional Picatinny rails surrounding the handguard so you can add things like lasers, bipods, and lights. If you're looking for a budget friendly CO2 BB gun with full auto and semi auto capabilities that looks and feels like an AR type gun, get a Crosman A4-P Full Auto at Airgun Depot now.

Again excellent auto air-pistol bb gun easy to use with a small barrel, to have to treat vermin on my property and target practice.


By JosephUSAMarch 23, 2021

First off, the gun is awesomely beautiful! Realistic SB AR pistol feel. I've seen conflicting specs of the velocity...even from Crosman. 400fps most places; 430fps other places...which is what the velocity is of most of the other Crosman BB rifle pistols of this type. Chrony'ing it using Crosman Copperhead BBs, it wasn't even getting near the 400fps...I was only getting low 300fps numbers. I also ordered the magazine with the 300rd reservoir; with it I began getting just above the 400fps mark. So apparently there is an air flow issue with the included 25rd magazine I received. I'll be looking to see what type of velocity others get in future reviews. The trigger is horrendous; it must have 25lb. half inch pull to it. In full-auto, it doesn't feel as bad. My initial testing with the gun, semi-auto accuracy does not seem on par with some of Crosmans other semi-auto and full-auto BB offerings, from reviews of others I've seen on YouTube...appears abit more erratic; but it could be me.

Cool looks...full-auto rock & roll...ability to put a full ar buttstock on it if desired.

Yes, this is just a chopper shorter version of the R1. I'd research on the 300 rd mag or quick load mag you are talking about before purchasing. It rarely loads more than 12 to 15 rds and is super pain to use. At $60 one would hope for a better mag but this certainly isnt it.
