The Strike Industries CZ Scorpion EVO Charging Handle (Medium) provides a longer, ergonomic and positive tactile feeling over the original CZ factory charging handle. The SI charging handle will ensure more accessibility, even with additional rail accessories like a side mounted weapon light. It's not too big to get in the way and has been designed to reduce the risk of snagging with the rounded edges. Retain the factory ability of being ambidextrous and non-reciprocating. Made from durable and lightweight polymer reinforced by nylon. Fits all CZ Scorpion EVO models.
