"Proprietary design that to our knowledge thus far, will not fit into any "conventional" M4 receiver. We have tested fitment on JG, Echo1, Ares, VFC, Classic Army, G&P, Elite Force and EMG and none of these receivers will accept this gearbox without extensive modifications. Alignment pin location and take down pin location are specific to the S&T series M4 receivers.

Internally the gearbox is what you would expect from S&T. Externally the shell is of very poor quality. Shape and finish are rough and out of spec with other brands.

I would not recommend this product for anyone that is not prepared to do extensive modding to get it to fit.
