Description
Complete receiver block for the Huben GK1 in .22 / 5.5 mm or 6.35 mm / .25 caliber.
If you have an older V1 GK1 pistol, you can easily upgrade it to the latest version! The V3+ features a redesigned slide and, just like the V2 and V3, has an upward-facing magazine catch that almost never breaks—unlike the V1.
Just swap out your old block for the new one, and start shooting!
If you're not comfortable with the technical aspects, we can also install it for you for an additional fee of €100. (Shipping costs to send the GK1 to us are not included.)
If you would like to take advantage of this additional service, you must pack the air rifle VERY carefully and send it to us (with insurance). We will send you our address if you wish to use this option. We will then install the parts and return the repaired and calibrated rifle to you.
Of course, you can also bring the GK1 to our warehouse (by appointment) and pick it up when it’s ready.
