Entry Accuracy Enhancement Kit.
Not quite an R-Hop barrel assembly. This kit features a Krytac stock barrel assembly, modified for Flat hop. From our findings, this does enhance the overall range of most AEGs but does little in terms of accuracy gains as opposed to R-Hop. Entry level enhancement set. Suitable for most M4 V2 Type AEGs/HPA guns.

Includes: 6.05mm Brass Krytac Barrel; Krytac Rotary Hop up unit; Flat modified Krytac Blue Bucking: Umbrella Flat Arm, C-Clip, Spacer O-Rings.
