DIY Marushin UZI bolt breech block retainer

Hi everyone,I just broke my uzi bolt breech block retainer(#81),so I use AEG piston teeth to made a new one,because piston teeth need to bear the AEG around 1500RPM firerate,so I think it is strong enought,and easy to get(if your friend upgrade a AEG,than you get a material) and the dimension is more fit than original,here is process:


NOTE:use Φ4mm tungsten steel or carbide endmill to drill only,HSS endmill or drill will NOT cut off the piston teeth because it made by very hard material





thanks for watch!

Brilliant, that is very good to know, thanks for the info.

Nicely done
