Steel shims for improved bolt impact by forward assist button on AR15 / M4 GBB guns.
In GBB guns, the forward assist button works the same way as in real steel guns - it allows to push the bolt with the nozzle deeper into the hop-up chamber. The forward assist button is most often used after the initial weapon charge, when, for example, due to "gentle" release of the charging lever, the bolt with the nozzle does not get into the correct position.
The EPeS shim increases the possibility of pushing the bolt by 1 mm. This has a positive effect on better sealing and correct feeding.
- Made of spring steel
- Made in the Czech Republic
