When you pick up the SR4 you can feel the solid build quality. Upper and lower receivers, buffer tube, outer barrel, RIS rails, gas block, and flip up sights are all metal, and built to last. Even the polymer grip and Crane stock are made from solid, high impact ABS, just like the real thing.
You’ll find the same build quality and attention to detail inside the gun. This Black Ops M4 comes stock with a full metal Gen. 3 gearbox from SRC with with 8 mm metal bearing bushings, metal spring guide, upgraded metal piston head, cylinder, and cylinder head, and pre-shimmed all steel gears. The hop up is metal with a newly designed wishbone style hop up arm that eliminates creep while improving consistency and range, and a new high torque, long axle motor from SRC is ready for Li-Po batteries and optimized for .25 g or heavier airsoft ammo.
High quality upgraded internals combined with a slightly tighter 6.06 mm ID metal barrel translate to excellent performance and range. You can expect a consistent muzzle velocity over 370 FPS with .20 g BB's, and more than 600 rounds per minute on full auto. (the exact FPS and RPM will vary with your battery and ammo).
If you want a completely custom gun, or just room to grow in the future, the Black Ops SR4 AEG is ready for anything, inside and out, compatible with most M4 internal components including spring, gearbox, motor, hop up, and barrel upgrades. You can use most standard M4 style magazines including real, mid, and hi-cap mags. The crane stock is ready for your choice of nunchuck style batteries, we recommend 9.6 V Ni-Mh or 7.4 V Li-Po.
