Hop-Up chamber for AK airsoft replicas. This new Hop-Up chamber is made from EN AW 7075 aerospace-grade duralumin, which offers strength comparable to steel with the weight of aluminum, making it the best material for this application.

This chamber is precision-engineered and custom-made to ensure optimal performance and feeding.

For the best inner barrel fit, a new innovation has been introduced in the Hop-Up chamber – the collar nut connection. It is positioned in front of the Hop-Up chamber. Simply install the inner barrel with the Hop-Up bucking into the chamber, secure it with the C-clip lock, and finally screw it onto the Hop-Up chamber using the collar nut (a 10 mm wrench is required). The collar nut is made from EN AW 7075 aerospace-grade duralumin and, once tightened, seals the inner barrel very firmly. No excessive force is needed when installing the collar nut—apply only light pressure; otherwise, the inner barrel may rotate inside the Hop-Up chamber. The sign of optimal sealing is the reduction of the gap in the collar.

This Hop-Up package includes:

1pcs Hop-Up chamber for AK (anodized, made from EN AW 7075 aerospace-grade duralumin)
1pcs Adjustment lever (anodized, made from EN AW 7075 aerospace-grade duralumin)
1pcs Pressure lever with cut for standard spacers (anodized, made from EN AW 7075 aerospace-grade duralumin)
2pcs M2.5 x 3 mm screws (black chemical finish, steel material 12050)
1pcs M3 x 12 mm screw (steel material with 8.8 strength rating, black chemical finish)
1pcs Plastic C-clip for AK (ABS material)
1pcs Plastic pin (ABS material)
1pcs Rubber O-ring (vulcanized rubber)
1pcs Collar nut (anodized, made from EN AW 7075 aerospace-grade duralumin)

We recommend purchasing a spacer set, Hop-Up bucking, and a spare plastic C-clip lock or collar nut together with this Hop-Up chamber.

The Hop-Up chamber is delivered unassembled, meaning it must be assembled before use.

Warning! Do not use oil or petroleum jelly to lubricate Hop-Up components, as this may damage them and reduce the Hop-Up effect.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.

Smell
Size: Queen (2 Count), Color: Original White (Cooling)
The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back. Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.

Actually Cooling Pillow
Size: Queen (1 Count), Color: Original White (Cooling)
This is a really nice pillow, I was worried it would be too soft or too firm but it's just right and it's actually cooling, it feels cool every time I touch it. I've noticed an improvement in sleep since using it. Would recommend!

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them. The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back. I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.
