Bolt Airsoft excels in bringing realism to the Electric Airsoft rifle market through their patent pending Bolt Recoil Shock System (B.R.S.S. for short.) Their goal is to combine the advantages AEGs have such as performance, consistency, and reliability with the often sought after recoil impulse from a gas blowback system. This unique feature works by transferring the kinetic energy from the piston cycling to a weight system in the stock to generate the simulated recoil. Paired with high quality externals, Bolt Airsoft offers a line of excellent ready-to-play guns that also make for great starting platforms for project guns and upgrades.

"Between this. And the vfc. Being the only productiin sr-16 with correct lowers (not including trademarks)s. I chose this one due to the ebb/less work precived to get it running.
I am a skirmisher/airsmith, not just some guy that plinked down for a nice gun.
Out of the box i was rather impressed. Externals where about on par with g&p but noticed the finish on the urx3.1 rail scratches pretty easly.
Outside of externals. The ebb. It does accually kick. However. Not as hard as a gas in mag gbbr. (Feels harder then the erg, but not much). (Has nothing on my daytona gun fal)
On 9.6v batts the operation is sluggish. On 25c 11.1v its crisp but there is still room for improvement.
However. When accually shooting it...
Bbs hooked to the left badlly, and there was grease everywhere. Barrel, bucking, hop-up unit, and nozzle. And it wouldn't feed. Also was missing the steel flash hider, and spare wiring harness in mine. The hop-up chamber itself was missing one o-ring and had a miscut hop up nub. For $385.... Its pretty bad to have these quirks...... Not to mention not in the box. Shot okay after the degreasing of the chamber. Dropped the 6.0 barrel for a 6.03 tk twist. As mine was chronoing in at 347 fps on .2 out of the box. Now its a solid 200 foot gun.
Well... Almost. The bolt hi-torque motor is pretty much a wet ferrite motor. And pretty old tech. Going to replace with a neo magnet high torque.
Externals : 8/10
Skirmishability 0/10 (10/10 after the rebuild)
Realism: looks good. Kick is good for an aeg 8/10
Would i buy one agian? Proboly not
