Hi

I'm loving the gun and the adaption you've made

How was it possible to add the bottle to it / I went the opposite way and added a longer PB air tube to get more air

But your version would be great on a webley eclipse which is a smaller version of the np03 in the uk

But if you could put all this together on a short barrelled version it would be a great little backpack gun 

Well done for that

Paul




 
I purchased a Kral Ekinoks for parts when P.A. dumped their stock like they recently did for the Kral Mega w/ the 330 tank . The earlier rendition of this rifle had a Huma regulator and 580 cf tank . Chronographed Hades at 860 fps , reg at max 170 bar .The combination was lacking plenum space . So I removed the regulator and went to a bigger tank . I did recently locate aftermarket high flow tube tanks from Russia https://www.ebay.com/itm/KRAL-PUNCHER-MAXI-lightweight-power-kit/274489104866

Here is what it looked like before :

Hi

Thank you for your reply 

The gun looks the business either way

The second pic it looks alot sleeker 

Have you fired any slugs from your creation it would be interesting to see if it likes them 

I put the lw 18".barrel on mine just for that reason but not that everyone likes them I swage my own from 217 to 218.5 with different bases and hollows from 18.6g upto 24g in 22 cal I'm still in the process of finding the best slug at a lower power level but coronavirus holding me back abit over here

Yes I've seen the tubes from russia I bought my longer pb tube from him he is a great bloke to deal with and knows his stuff

I have an evanix ar6 and the air tube size is ridiculous so I'm looking someway to either get a longer tube or put a bottle on it somehow .

Keep up the nice work and let me know if you try slugs out please

Kindest regards 

Paul
 
22 cal update : I decided to ditch the 1100cc bottle and go back to a 580cc bottle , put the carbon fiber tension shroud back on . Running non-regulated and I did voodoo on the drop block .

First time out with the 22gr Hybrids was 1043 fps , no bell curve all down hill . On shot 13 the valve failed and dumped all the air in the tank . I replaced the cheaper black valve with a metal one , changed out the hammer spring from 28# to a 23# . cut two coils off the valve spring (a 7# , think the oem was a 9# rate)

It's doing 945 fps with a nice bell curve graph. I haven't run a full shot string just 40 because curret market conditions .

I'd like to try some JSB 25.39 Redesigns when things get back to a new normal .
 
Yes I did , but I lean towards lighter weight for hunting carry . Easy enough to bring a scuba bottle along for refills ; IF needed .

For bench time just shoot tethered . I absolutely think bench guns should be heavier than hunting rigs . I prefer hunting myself as I already spent years shooting powder burner benchrest . Went down that rabbit hole before .
