Since this guy was a pistol when it was born, I’m posting in the pistol section…

My .22 GK1 - Version 1 #67 has shot >30,000 GTOs. It has my “active shroud” mod but everything else has been stock and it’s been used exclusively as a pistol. I’ve changed one Oring but aside from that it’s been a hiccup and jam-free delight. Just a barrel clean every couple tins and it’s just as accurate as when it arrived.

However, the time had come for a change, and I was even considering selling it. But after picking up a 3DP stock from Daniel in Bulgaria, I’m enjoying it again. The stock is nicely printed and a great fit to the gun and my body, which is that of Mr Average. I don’t care for any folding capability.

Popped on a 12X Optimax scope and tuned it to shoot the AVS 22grain .223 slugs that I’ve had lying around for some time. I tested a range of slugs over a year ago and found them to be the best of the bunch. I click em in via the stock gate with no “seating” and they stay put at the rear of the mag and shoot very well. The power adjustment is set to shoot them at 900fps and I get a tight string at 890-905fps (40fpe) between 270 and 190 bar, which is 15 shots. The target in the pic below is 8 shots at 70y. My Vet2 tactical sets a high bar for slug shooting but this is pretty good for a semi auto “pistol”

That's a decent looking rig right there!

Now, would you buy a 12.25" barrel and extension kit? (a plug and play barrel and extension to compliment the carbine attributes and add more power or level out higher power shot count).

In winter, I take it in a backpack for X-country skiing, so I don’t want to make it longer.

Thanks for sharing, this maximizes trigger time 😀

Man, I can't imagine shooting 30k GTO pellets in my lifetime much less in about a year lol. I'm happy to hear you got it sorted out!
Phenomenal accuracy with those AVS slugs! Do you happen to know the LOP on the stock?
