Hop-Up Adjustments

To adjust the hop-up, remove the

magazine and locate the hop-up

adjustment set-screw. Turning the

screw clockwise will reduce the effect of

hop-up, while turning the screw counter-

clockwise will increase the effect of hop-

up.

Hop-up is a special feature that extends

the effective range of the Professional

Training Weapon by putting a “back-

spin” on the BB bullet. The back-spin

will create additional aerodynamic lift,

effectively makes the BB “float” in the air

and increases its effective range.

For typical in-door, force-on-force training, the engagement distance will be so

short that the effect of hop-up will not be noticeable. As a result, for premises-

entry type of training, the adjustment of hop-up is typically unnecessary.

However, in larger area of operations such as urban warfare training/scenarios,

proper adjustments of hop-up is a critical component in maximizing the

effectiveness of the Professional Training Weapon.

After the adjustments has been made,

install the magazine and test-fire the

weapon in a shooting range. Notice

the trajectory and re-adjust if

necessary. Please also note that every

brand/type/weight of BBs will require a slightly different hop-up adjustments; for

example heavier BB typically requires more back-spin to “stay afloat”,and the

smoothness of the BB’s service also requires slightly different settings. As a

result, it is advisable to standardize on a particular type/model of BB so that you

do not need to re-calibrate the ho-up every time a new round is used.
