AirsoftPro Reinforced Hop-Up Chamber and Cylinder Head Gen. 2 for VSR-10 Series (BAR-10, MB-02/03...)

The AirsoftPro hop-up chamber for VSR series is a high-quality upgrade part that is CNC machined from aluminum (6061-T6), which allows you to improve your rifle’s accuracy and range. A precisely machined unit keeps the assembly sealed and prevents the parts from moving, which guarantees consistency between shots. This chamber also has two separately adjustable hop-up levers, which means that you can adjust the BBs spin as much as you want, with a curvature or without!

The chamber uses an electric gun’s bucking (AEG bucking) and inner barrel. In practice, this is an advantage, because there are several available buckings for electric guns and especially different length inner barrels. The chamber also comes with a steel cylinder head, which is specifically designed for AEG buckings, so the seal is optimal. The nozzle part is a tad longer and narrower than in the separately sold AirsoftPro cylinder head.

Features:

• CNC machined from 6061-T6 aluminum and anodized to be shining red.
• Separate centering ring for the inner barrel – the barrel doesn’t move and sits still, which improves accuracy.
• Separate centering ring for the nozzle – improves air tightness between the nozzle and hop-up chamber.
• Two rubber pads between the chamber and the cylinder head – reduces the tremor in the inner barrel and improves accuracy.
• Easy to install, installation can be done in under 10 minutes (see video below).
• Requires the use of a barrel and bucking meant for electric guns.

Upgraded features for the Gen. 2:

• Two metallic hop-up levers – they also allow sideway adjustment. The unit has three adjustment screws – one for both levers and a third one that adjusts the levers at the same time!
• Cylinder head equipped with two O-rings.
• Adjusting is done with the included 1.5 mm hex key.
• Redesigned body: i.a. the barrel adjustments screws are sturdier.
• Bigger O-ring pressing the levers
• Better feeding

The inner barrel is attached to the chamber with three screws. You don’t need the C-clip grooves on the outer surface, so it doesn’t matter where they’re located (cf. M14 vs. standard). We recommend you use the threadlocker when attaching the inner barrel.

• Chamber, screws and centering ring
• Two hop-up levers and a total of three O-rings
• Steel cylinder head for VSR series
