About BOLT

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.

"This is a re -review of my recent post.
The stock is perfectly fine. The Dboys buffer tube was not thick enough for the pin to stay locked on one point. I bought a G&P Buffertube and it works great now 5 stars

"not sure how I feel about this stock. It was my first time putting a new stack on my gun. it fits two of my tenergy 11.1v lipo batteries which is why I got it. looks nice. fels nice. the only problem I have is that it WILL NOT lock into any of the six point holes on my buffer tube. It may be the buffer tube but when I extend the stock, I draw it up to aim and the stock will slide forward from the little pressure I give holding the gun tight.

Looks good
holds batteries well
not too hard to install

Does not lock on the buffer tube
Basically does not do what a stock should really do
