Great cylinder for fitting inside adjustable M16 style stocks,
Review by
I bought this cylinder, not for what it is described for on this site but for using on a paintball mag fed marker. The purchase was well worth it, it fits snugly through the extending butt stock and allows it to lock in place.
All seals seal well no leaks with the added benefit of already being black so it does not stand out as a air cylinder.
All in all a great purchase from a great company, I will be shopping here again!

Unless otherwise stated, all products are sold singly.



Any figures used are based on tests performed on the products when they are first listed. These can vary due to changes by the manufacturer, gas pressure, gas used and a number of other factors. All figures should be treated as an approximate guide and used for reference only. 

All listed FPS are +/- 5% due to differences from rifle to rifle. If you require a guaranteed FPS, please add an upgrade/downgrade option on to your product (this may cost extra).
