Mentioned over at JK Army, the RIS variant of the GBB open chamber M4 PCC from WE is coming soon. It weighs in at around 5kg and is likely to cost around 300USD.
It’s all metal, intended for HFC gas use, running at around 380fps on 0.2g BBs and the magazines carry 50 rounds each. It is worth noting that it looks like it is not compatible with the “G Model Magazine” and you’ve got to buy the specific model for this rifle.
