This is the coveted gen6 2020 Huben K1 .22cal with the unchoked slug barrel (17.7" twist rate). I re-crowned the barrel and polished the bore & rifled magazine. The rifle is as accurate as the Hubens can get!
The regulator can be adjusted up or down. The titanium air cylinder allows for fills to 5000PSI.
At lower pressure, the shot count is pretty high. For long range (200+ yards), I've found that likes the 28.5gr Varmint Knockers between 1060-1100FPS.
Upgrades & Extras:
Price: $1325 shipped (CONUS only) where legal. Paypal F&F or add 3.5% plus your state's applicable sales tax.
