If you make a washer out of a Tortex bass pick and insert at the swivel point, it gets rid of a lot of the wiggle.

I routered the grip to fit the Cobra’s “plug”

Groucho, the Glock version looks like a tough job to adapt to the Huben. Fab Defence makes a version of the Cobra Folding Stock for the Ballista Bat Reverse crossbow. It can be found on eBay. That’s what I used.

No, it is the FAB Defence Cobra Folding Stock. Originally designed for a Glock, adapted for a crossbow pistol, i adapted it for the Huben

I had this in another topic of the forum. Position 1 and 4 are my most often used.

I routed the bottom of the grip to accept the grip plug of the Cobra stock. The stock is the Balista version. There is a little Gorilla tape and zip tie action on the cheek weld to lock the stock in the semi collapsed forward position shown in my photo. This gives a nice stable foregrip. This...

#11 celebrates it’s 10,000th shot!

Hey all, I just wanted to share with you that if you are running lower power ( 600 fps ), and are seating JTS 14.89 dead center wadcutters, you can remove the load gate. I have been testing this for 2000 rounds. No jams, very fast reload. I have really been enjoying this gun for thousands...

More pellet tests for the GK1: There are definitely pellets that won’t jam. The JTS wadcutters in .22 14.89 grain fit nice and tight with no slip or jams after being seating each one. Shooting at 400FPS. Dime size groups at 10 meters off hand, unsupported. Easily gets through 2 mags. The JSB...

Yes. That seems to be where it is happening. Tighter pellets aren’t doing it.

Another 500 pellets through the GK1. At this point I can’t recommend the CPHP’s. Once the magazine got enough pellets through it, it loosened up and the pellets would shift around in it and jam up. Same with the JSB exact jumbos. I am currently 200 pellets into JTS dead center wadcutters. I...

There is no wheel on the pistol. You access the valve screw with a long Allen wrench that fits through a hole in the grip. When I got it out of the box, it was shooting 325 fps and having cycling hiccups. Two twists of the valve screw put it up to 900fps and LOUD. My gun did not come with the...

I doing ok with accuracy. I can place two mags worth all in the black with the majority in the 8,9 and 10 rings. A few flyers. I like to use the cheapest ammo I can make work, because I shoot ALOT. As to clicks, this gun doesn’t click like the K1. It has a smooth turning screw and minute changes...

I mostly shoot 10 meter with 10 meter regulation paper targets, off hand, one hand, unsupported. I use the stock sights. The rear is adjustable for left/right and up/down. The front sight is green fiber optic.
