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.

Puppy seems to love!
Color: 20 Pack Rabbit Style
Purchased to have when we brought new puppy home. This is perfect for her teething needs. I think she plays with container as much as the toys. As stated, these are toys for a puppy or smaller breed.

Objects are smaller than they appear
Color: 20 Pack
I bought these to donate to a dog program at work. I was so disappointed when I opened the box and saw that they were so small. I hate when the adds make items look larger than they actually are. On the flip side, this would be perfect if you have small dogs.
