PCP Huben GK1

[fderry]

I limit my PCPs to 20fpe based on some of the targets I have on my 60 yard range. Because of this I’m focused on .177. I have a HW44, Crosman 1720 and BRK Atomic in .177 among other pistols. I pre-ordered a Huben GK1 in .177 but learned when the first orders came in that Huben hadn’t completed the development of the .177 and the retailer wasn’t sure if they would be available this year. So, I canceled my order. But I continued to follow various forums discussing the GK1. After reading the accuracy some folks were seeing with the Predator GTOs and the general opinion that the GK1 was the best thing since sliced bread I decided to order a GK1 in .22. I talked with Kelly (Krazy Cool) and had him configure the GK1 with a ~1lb trigger pull, moderator adapter, after market magazine cover and spare mag release arm based on forum comments.

I received the GK1 about 2 weeks ago and I can verify it is (almost) the greatest thing since sliced bread! I set it up to shoot the 11.75gr GTOs at ~ 690 fps (14.2fpe). I am impressed with the trigger, smooth shot cycle and initial accuracy at 10yds with this setup. Not impressed with how loud it is without a moderator. So added an Impulse Air 1200 moderator

My initial accuracy at 10yds with a bi-pod and Optisan CP 3-12x32P scope was really good. Next, I tried it at 30 yards
Target at 10 yards.
38 shots. Started at 290 BAR and finished at 200 BAR,
Hi 710fps
Low 680fps
Avg 693fps
ES 30fps
SD 8.5fps



30 yard Target (3 - five shot groups)
