r/Vz61

Hit the range this past Friday with a buddy, ran the Skorpion with the 22 upper, Aguila 40gr subsonic, and Thompson Machine Zephyr XL

Just got my receiver back from Mr. Chefur himself. I had him build the gun as well. I had the receiver hot blued to match the upper. I also got early lightning cuts as I wanted the gun to look OEM as possible. This is an SBR and the stock has incredibly tight lock up.

In my opinion he probably has the best receiver. The finish and the machining is absolutely top notch not to mention the cool stampings he added to the gun. He did an excellent job putting this together for me and I can't recommend his receiver enough!

Find spring that sits nicely in the charging handle slot. For me this was a 0.4*4 spring.

Cut a coil or two off. Repeat x2

Place into bolt carrier

Test fit.

If everything moves nicely and the charging handle can't touch the upper reciever then you win. If it still touches you have too few coils. If it has a lot of friction or binding, you have too many coils and the bottom retainer of the charging handle is grinding against the inside of the upper receiver.

Just got my first vz 61 in 9x18 makarov, i am not a fan of these polymer magazine, unfortunately i could not find any metal magazines need help. Thankyou

Is this normal scorching on brass? Only on half the casing
