Not familiar with "Gunpower" products, but they all look they are copies/modifications of AirForce products.
They appear to have a maximum of about 18fpe in stock form- which is not very high for a 3000psi PCP. It is labelled as a "target" rifle- so this is possibly partially intentional.
In any event- as I see it, you can modify the valve/hammer configuration to ensure maximum flow for the maximum amount of time (duration) and get a longer barrel (12" is too short for effective power increases- more barrel would allow more time for acceleration of the pellet before exiting the muzzle). |

That made me laugh...
Gunpower is a UK based company and is owned by Geoff Darvil. Geoff is the ORIGINAL designer of the rifle you in the States know as the Air Force Talon series of PCP airguns.
Geoff hooked up with an American buddy and it was agreed that Gunpower Stealth products would be marketed there by a new company - Air Force.
AirForce have without doubt improved on the original design and new guns have been introduced in the States that are later sold under a slightly different guise here. |
