I like it. Nice accessories. Let's see a shot sting please.

I already had the mod and red dot, but yeah not a cheap build, I’m in the UK so it’s a pretty unique build

 

[wimpanzee]

now you just need a falcon shroud!

I see. Well, I just setup a GK1 very similarly but for 20 FPE.

Not particularly please with the extreme spread. Could experiment with valve adjustment and or reg pressure to tidy up.

That ain’t too bad, I was getting 12fps ES with unsorted RWS Hobby’s 11.9gr over 3 mags, ive only done one shot string, but used a few different types of pellets to see what it liked and the shot count/how many mags before I refill. I got 6 full mags from a 300bar fill, but that’s at poopty UK Sub6 power levels. My reg is also set at 125bar and the final power level is set by the power adjuster

To get that shot count from that little tube (280 bar fill) is pretty dang impressive me thinks.

Yeah Sub6 is neutered way down! I found 125 bar acceptable for mag indexing reliability.

 

[AJ_Roberts]

Half way through 7th mag it dropped under the reg pressure, I could hear it struggle to index at around 110bar, stopped straightaway and refilled it, so 6 mags gives me a nice safety buffer

Kelly at https://krazcool.com/ makes them, I bought one directly. He doesn't seem to list them yet, but you can call and as about them. I thought I had a pic handy but I can't find it, I'll upload one later!

Bad a** the best one I've seen so far,

 

[AJ_Roberts]

Cheers, there are plenty of other as awesome builds on here

 

[AJ_Roberts]

Picked up the Saber Tactical clamp on Picatinny, so I can now use my little tripod, I love using it shooting off tables, being a bit more upright it’s much better for my dodgy back

is this the 34mm clamp from Saber Tactical? looks like a nice solution as I'm not too fond of the 3D printed items.
the size you have seems to fit nicely!

Yep, its the 34mm one, it fits perfect

 

[AJ_Roberts]

Thats it for now

 

[AJ_Roberts]

Got my buddy on AGF Forum in the UK to make me a fill port plug, it’s the simple things that finish off a build

 

[elwoodblues]

Where did you get the picatinny scope mount?
