Upon receiving the Poly Technologies AK47 Barrel Bushing Lock Spring – Chinese AK Rifle, my first impression was positive. The spring appeared robust and well-made, exhibiting the characteristic black finish typical of Chinese AK parts. Compared to generic springs, this one felt noticeably sturdier and had a more precise coil pattern. While I didn’t have another exact Poly Technologies spring to compare it to, I had a few other aftermarket options on hand. This Poly Technologies spring felt superior in terms of material and potential longevity. I chose this over others based on the name brand recognition of Poly Technologies and the assumed quality control.

Excited would be an overstatement for a tiny spring, but I was certainly relieved. This component was essential to completing my build, and the initial inspection instilled confidence in its ability to perform its critical function.
