Glock Gas Mags

2 x Standard Raven Glock EU17 gas mags. £20 each posted. 1 x Standard WE Glock EU17 gas mag. £20 posted. 1 x Extended Raven Glock EU17 gas mags. £30 posted. None of the mags leak and have only been used with green gas. The end plate on the extended mag is a little damaged, but these can be bough from places such as Patrol base for around £4. All mags may fit other guns, but you'd need to check this yourself. I could do all 4 mags for £80 posted.
