Specna Arms Alloy HOP-up Chamber for AK / SA-J Series AEGs

If you're running an AK and seeking a robust HOP-up unit, the Specna Arms Alloy HOP-up Chamber for AK / SA-J Series AEGs is a fine choice. Made from strong alloy, this replacement original part is the external HOP-up chamber, and doesn't include internal or trim parts to complete the slider HOP-up unit. Compatibility-wise, this part is ideal for Specna Arms SA-J series AK AEGs, but should also fit most other AK AEGs which use a slider-style HOP-up unit.
