Panther Arms DPMS SBR

What I have here is a modified to airsoft Crosman DPMS SBR. I added a 20 inch 6.03 aluminum mirrored smooth inner barrel.

The magazine has been converted to an HPA intake. I bored out the magazine to fit 6mm airsoft ammo. The magazine is heavily modified with an advance airflow system. The plenum components have been upgraded allowing additional air volume, with a wider release nozzle and tighter piston spring. The hammer spring was upgraded and the blow back action is much stronger for a more realistic feel. Magazine comes with original outer casing .

It's unregulated and FPS is based on your tank output and amo grain. The 20 inch barrel fires with force and precision. The rifle has three fire modes, semi, burst, and full auto. It fires about 1400 rounds a minute on full auto. 

Easily capable of 1000fps+ unregulated.
