Description

This Maple Leaf Hummingbird Short-Stroke Bolt Assembly for GHK can be directly replaced with the original GHK GBB bolt carrier. It can increase the cyclic rate of fire, up to about 18 rounds per second (it will vary depending on the actual gas pressure and the length of the inner barrel/weight of the BB bomb). The traditional AR15 can be removed from the support rod structure design, and can be changed into a no support or a folding support design, which increases the convenience of carrying. After there is no BB, the bolt can be fixed in the back, which does not affect the original GBB operation habits. It is compatible with old and new GHK M4 series GBB.
