My new action arrived from India. I did a trade with the chap who makes them for a custom laminate grip set.
This is a prototype action based on the match pro,but with a shorter 50cm barrel and sub12.
Samantha and I shot it the other day. Did 80 shots from 190bar down to an indicated 100bar.
Yet to chrono it, need to find a suitable adapter for the chrono.
It's accurate... And the trigger unit is a mile ahead of anything else this side of a grand. It actually reminds me mostly of the feel of the walther lg400.
I've already stripped it for a peer Inside and a wipe down/re lube.
I've also floated the barrel. It's a 15mm dia necked down a little at the block and plenty rigid to float.
Anyhow pics of the Interesting stuff
One important thing of note.. whilst I've not stripped the cylinder fully there appears to be only 4 orings in the whole pressure side of it.
Gauge on the end
2 on the air cylinder,one either end
And one on the firing valve seat to seal the cylinder.
There's a couple of others as buffers and stuff but only the 4 that would cause a leak to the high pressure side
Unscrew cylinder to access valve return spring and valve pin.
You can see there's a small oring on the valve to reduce air wastage.
Valve seat and cylinder sealing oring ^
Here's the whole firing assembly. Hammer spring through to valve return spring
Beautifully simple and well machined.
Plenty of scope here for us who like to tinker
Trigger sears all removed and in correct orientation before cleaning up.
It looks like most the preci stuff will come well lubed.. tbh id rather that than it being dry and possibly rusting. The climate out there is problematic being sub tropical
I did make a crude little tool for refitting the cocking dog pin. Just ground a bit of scrap threaded bar and magnetised it so I can get up inside to press it back home. Actually set the depth on the tool so it goes back the correct depth. Works a treat.
The barrel is also o ring sealed in the block for reduced air leakage on firing. But there not a critical part that would cause a leak if they deteriorated.
She's basic but well machined ,easy to pull apart and there's nothing mad in there. It all follows pretty standard build principles.
I'm going to do some further testing and see what sort of performance it yeilds as it is. I'm going to find a slightly lower weight spring for the first stage in the trigger and then just give it some stick.
It's got the feel of a modern s200 and I like that , I like that a lot.. the trigger on this is a lovely thing and the barrels appear decent too.
The pistol and 6ftlb match model all shoot h&n very well.
I'm going to collect a bunch together for some involved testing.
