Fantastic craftsmanship and cool looking design.
This new hop-up chamber from 4UAD in Taiwan is a great upgrade for your VFC or GHK M4 GBBR.

The anodized gold colors are visible when retracting the bolt, making sure to turn heads on the field, as well as hit heads with it's price TDC hop-up adjustment system.

The Top-dead-center TDC adjustment system guarantees that the hopup nub is always centered during adjustment, increasing consistency across weight changes and hopup setting.

Adjusting the hopup setting is done simply through the ejection port or by lifting the upper receiver up, with no tools required (though a little pin or stick does make it easier to reach).

The barrel is locked in place with a unique, patented tri-lug locking system, ensuring a rock solid performance for a long time in both milsim or CQB.

CNC machined from durable aluminium and surface treated with gold and black anodize.

Included in the set is various spare parts for assembly, including a spacer for use with GHK systems (do not use with VFC).

Hopup bucking is not included, but i recommend the 4UAD Friction Pro bucking - also from 4UAD, which is confirmed to work well with GBB across all weights and fits in this chamber.

Not for tough chewers
Color: Blue
Cute toy, good concept but definitely not for super chewer. Got it at such a price that I let him destroy it because he was having so much fun. You only have one birthday a year after all.

fun toy
Color: Orange
Very cute toy .My dog loves it. He is hard on toys and loves playing pully. So far it is holding up really well. It is a good size for medium to large dogs. I think if you have a small breed it may be to large. The color is a vivid orange and white. I really think your dog will love it.
