Magazine
Fits the STUD Loader/Feeder system for automatic pellet loading. 
 IMPORTANT NOTE - Clearance under the scope tube to the bottom of the breach needs to be 1.900" (48.25mm) MINIMUM with a 30mm diameter scope tube. This is because the STUD mags have more rounds than the RAW factory mags and are larger in diameter than the factory mags.
STUD Recommends the use of "FX No Limit Scope Mounts" or euivalences, to easily adjust the scope position to accept the STUD mag. If you are unable or unwilling to adjust your scope to a 1.900" minimum opening please do not order the magazine,
These mags will only fit the new RAW rifles (HM1000X with the wider magazine well (.675" wide)) and they WILL NOT fit the older HM1000 rifles. STUD does not intend to make magazines for any of the older RAW versions.
Tha RAW STUD Mags are only available in "Right Hand Feed" versions.
Visual "Shots Remaining" indicator
Magnetic Lid, no twisting of knobs like factory magazine
Large internally driven, custom wound coil spring (no adjustments required)
Rotor rides on (1) class 2RS, roller bearing, allowing glass smooth feeding of rounds.
The magazine WILL NOT feed really short slugs like 25g Zans. These slugs do not have enough of the slug main diameter, to feed correctly
