Our take:  Systema is renowned in the airsoft world for their top-of-the-line craftsmanship on all their manufactured parts and products, and is also attributed with having a world-class R&D process through which all products undergo prior to making it into their product repertoire.  It's no wonder why more airsoft enthusiasts choose SYSTEMA as their upgrade part of choice, over the many other brands of upgrade parts available.

Specifications:
- Effective upgrade for stock to mildly upgraded AEGs
