Hello I bought mine approximately 3 month ago the we is nice but the middle part of the we where it connect the side piece together broke. It might be better the add more thicker wall or different type of metal. I use 400 fps spring on the Gbls das
Thank you for using our products. Our in-house verification has confirmed that the product is still usable without breaking after 300 FPS and 10,000 rounds. How many rounds have you fired after purchasing our product?
We will review the materials and heat treatment in the next and subsequent batches to ensure that they can withstand higher initial velocities than expected in Japan.

これは爆音仕様(M120)スプリングでも対応可能なのでしょうか。
実際に試したわけではありませんので正確な回答はできませんが、初速1J以内のスプリングであれば仕組み上は問題ないと思われます。
