    Umarex Umarex Komplete refillable PCP conversion

    So I bought my own for a knock around camping gun that I didn't have to worry too much about and could carry an extra nitro bottle with no need for a ton of extra things needed. No tank, compressor, or handpump. Works great for that. I ended up liking it far more than just a camping gun. Since I...

    Very accurate Raw barrel measurement

    Does anyone have a Raw barrel lying around they could accurately measure for being able to make a drop in replacement? Trying to not have to buy one to make one.

    PCP Rifle $300 600mm FX 3 groove Hammerforged barrel. CF sleeved

    My custom designed 3 groove Hammerforged by TJ. Tested very well with both pellets and slugs. It's a .217 bore so anything .218 or larger didn't perform nearly as well as the proper sized slugs. 1in18" twist. Best for 24gr and under. FX Hybrids did exceptionally well. This is a test barrel prior...

    PCP Rifle $275 700mm FX DRS 3 groove Hammerforged barrel upgrade

    My custom designed 3 groove Hammerforged by TJ. Tested very well with both pellets and slugs. It's a .217 bore so anything .218 or larger didn't perform nearly as well as the proper sized slugs. 1in18" twist. Best for 24gr and under. FX Hybrids did exceptionally well. Uses a few barrel designs...

    Tuning Why I love tensioned barrels

    Used a 28" TJ .30 barrel. Tensioned using 1/8" steel tubing for added weight and stack of Bellville washers between the shroud and breech.

    Kral Arms Another fun day in the shop.

    The Kral Bighorn has a 580mm/22.8" barrel. The choke on the .25 is a touch tight but shoots pellets well anyway. I decided to make the shroud functional so my solution was remove most of that choke (Lost no speed after). Take a bad oversized .357 barrel end and re-thread both 1/2x20 (inside the...

    Kral Arms Quick, cheap power upgrades

    Seems lately I'm getting several Kral questions again. Here's a quick cheap trick to add some power. The trick is cheap but you need expensive tools or to make a friend with someone that has them... lol Tap the valve 1/4x20 at the valve stem exit. Epoxy in a 1/4x20x3/8ths brass screw. Turn the...

    Tuning .338 barrel blank

    I picked up a .338 barrel blank years ago. Had been sitting a while before I got it. Bore is clean but plenty of surface rust on the outside. No big deal because it still fits inside a shroud I have. I'll and off the rust. Treat the surface and leave it full diameter for weight. I want to build...

    Kral Arms Purpose built airguns

    I really enjoy having a rifle built for the purpose it's intended for. To me that means accuracy, power, and shot count match it's intended use. Since for me that's different for a lot of applications I keep them based on budget guns that I build out with custom parts so they do what I need...

    PCP Rifle Logun MKII .177 Price Drop

    I bought this rifle a few years back for Hunter Field Target. .177 with a New Element Helix 6-24x50 scope with adjustable rings. I decided to shoot WFT. So built a custom gun for that instead. It has a small blemish on the stock you can see in the pics. Beautiful gun but I don't use it and hate...

    Kral Arms Why did this take 9 years to think of?

    Cut the front off the fill assembly. Used Birchwood Casey Aluminum Black to refinish. Then drilled and tapped for 1/8 BSPT. NO MORE PROBES

    Kral Arms Another parts gun.

    I have a few bins full of Kral parts. Every now and again I find a part and it causes me to build a full gun around that single part. I picked up some Winchester Mod100 barrels years ago in .308. I had profiled one to fit a Kral action probably 2017ish. I see it from time to time while looking...

    Kral Arms Another one needs a name

    14" barrel NP-03 breech and cut down the factory stock. Dual front bottles and a rear. Will end up with probably all three bottles being 300-350cc Carbon Fiber to keep it light and 1000cc is still plenty of air. This is in .177 slinging slugs right at 950fps. Just a mock up still a little stock...

We all know what the FX does but surprisingly that .25 cal 14" barrel 180cc 3000psi tube little Kral does 20 shots a fill at 38fpe with an ES of 22fps using 25.4JSB or 10 shots at just under...

    Started as a Kuzey K600. Lots of FWB and AA additional parts to make a WFTF rifle. Planning to take it to Ireland this year and she needs a name. 8.4gr AA at 45 yards.

    FX FX DRS custom 3 groove slug barrel

    Okay, so I'm back with my 3 groove .22 barrel. Hammer Forging is definitely my favorite. Nearly always concentric to bore. Very smooth with little lapping if any. Mostly just a polish after maching to fit. Here is a factory port vs mine. I got a lot of advice from people I truly feel know their...

    What's your favorite shot group you've had?

    I've shot several near hole in hole groups over the years but this is by far my favorite. 2289 Crosman backpacker. Only 15 yards. Nothing ground breaking by any means but the way I got to capture it will probably always make it my favorite. Shooting an old hardwood pallet. Aiming at a knot in...
