Precision Pellet FX Impact High Capacity Magazine 177, 4.5MM FXIP-177P

Difference Between Slug and Pellet Magazines

The primary difference between slug magazines and pellet magazines lies in the hole diameter.

A slug magazine features tighter hole tolerances, specifically designed to hold slugs securely in place. This prevents the slug from shifting during feeding and ensures stable, consistent alignment when entering the rifle probe.

A pellet magazine, on the other hand, has a larger hole diameter to accommodate pellets. Because of this larger diameter, pellets cannot be used in a slug magazine.

While slugs can be used in a pellet magazine, they may shift or sit loosely—similar to a standard magazine—which can affect feeding consistency and accuracy.

Please note:

You may be unable to fit our magazines to your gun if you are using an aftermarket non-standard or non-factory original part, such as  Inlet Transfer Port. Before purchasing this magazine, please make sure all your rifle parts are original. We do not accept returns if magazines get dented or scratched for that reason.

This is a high-capacity magazine designed for the FX Impact platform.

It is made of aluminum and cut by a CNC machine.

Please note:

This product will not fit the early model FX Impacts (MK1/2) unless they have been fitted with the adapter plate to accept larger capacity magazines.

This magazine may not be compatible with non-original pellets probes . Please measure the pellet probe on your rifle carefully before placing your order. Do not order this magazine if the measurement exceeds 4.40 mm, as compatibility cannot be guaranteed.

This magazine is designed to be loaded once at a time by rotating the round pellet holder in the center. Make sure you block the hole from underneath with your finger.
In some calibers, like 177 and 22, you can remove the magnetic cover to load, like in the new FX magazines with short pellets. The 177 will not work with flat-headed pellets.
