XS60C PCP Repeater project

[silent_airman]

John, I am certain you will not regret getting your gun from Mike, and I strongly suspect you would enjoy having a repeating 60... based on the local reaction to mine.

Like the local reaction to the Stealth? You have a good bunch there who know a good thing when they see it!

Guys, when Eric tells you the locals like something he has built, you'd best snap it up!

They are a good group to bounce good stuff off of. Around here, the last thing you go cheap on is armament, and PBs are a fact of life. One by one, I'm getting them to take AGs seriously.

Well my money is on you, brother.

Guys, who has the best deal on QD fittings? Now that I'm buying multiples of everything, it's starting to matter.

Also, just ordered mags, and grabbed a .25 for an attempt at a bigger bore 60. Don't know yet if I can fit it with replaceable barrels, but will soon. In any case, a pinned barrel will allow it. Now I need advice on .25 barrels (what, where, how much?).

I'm taking Bob's advice (again, as usual...  ) and got a Prod mag coming, too. The manufacturing tolerances in the receivers are big enough that this may allow a lot less final fitting, and save time (AKA: Cash). We'll see...

A little off the path here, but how hard would it be to add a tank block and use 9oz paintball CO2 tanks?

It's do-able. Not cheap, but I can make something, if nothing can be adapted.

I was just curious for down the road.

I would think the QB or JDS tank block could work.... I'll know when I get my FD-PCP and measure the tube ID.... Of course the CO2 tube may be different.... Clearance for the tank will depend on barrel height relative to the top of the main tube....

You might want to have a look here:

Made in China but realistically so are probably 90% of the ones you find at domestic sources so why pay their markup?  Since Foster fittings are commonly marketed as paintball parts (850 - 1000psi), you'll probably want to confirm the SWP with the vendor before purchasing.

There is a post showing one who has added a HPA tank bottle.  Looks like its close to the barrel.  You may have to look for a 2" max O.D. bottle to run tanked CO2. 
http://www.gatewaytoairguns.org/GTA/index.php?topic=60023.0
I was thinking if someone was to make a fitting for a regulator or tank bottle to connect to the factory fill cap.   Mike has or had (he has supplied one to me) a tube that is 3 5/8" long and threaded on both sides.  It might limit max power being short but it will keep the bottle from sticking way out.  If interested you may want to ask Mike if the short tube is a little thicker than the factory CO2 tube for running higher pressure HPA.  It did seem to be a little snugger fit into the barrel band.

Thanks, Jason. I took a long look at that, and there will be real savings to be had. The shipping time will require a bit of planning, but I'll grab a few domestics for now, and do just that.

Every penny in gets folded back into this little deal, so every penny saved means progress...

I also found things of interest on this site, I wish I saw this before I made some recent purchases. Oh well, it's bookmarked now.

Thanks Jason
P.S. I wonder if Mike has seen this site.

Beat me to it Jason...

Hey guys, it was Tony that pointed out that site to me.  Just passing it along.

Tony, have you tried any of their wares yet?  I got in some 3000psi gauges today.  If they agree reasonably well with the gauge I got from McMaster a while back, I'll be using them to replace the silly 6k gauges that come on the Ninja bottles.

[toine]

Hey Jason.
I have not ordered anything as of yet, and was going to ask you the same. Let us know how those gauges work out.

Every time I see this post come back up I'm hoping to read your ready to take on customers...

Please let us know when that day comes!!!

I've read that operating pressure should be less than the maximum on a scale.  Don't remember where now, but the quickest thing I could google just now is this: http://www.ashcroft.com/tech/upload/AshBulG_7.pdf

"ASMEB40.100 recommends that normal operating pressure be confined to 25%-75% of the scale. If pulsation is present in the process, maximum operating gauge pressure should not exceed 50% of the full-scale range."

FYI, I am looking at doing the same thing.  I have a new 2.5" gauge for my SCUBA yoke and was thinking of adding a similar one to my 13CI tank.  Those little 6k gauges are impossible to read accurately!

Just thinking out loud here, but, what would you guys think of an 8 shot .25 carbine (20" Mrod barrel) with a bonded barrel?  I plan to build a 24" or more .25... but can't stop pondering this.

It would cut way down on shop time... and the barrels are reasonably priced.

What could a rig like this be expected to do?

[rsterne]

The velocity difference between a 20" barrel and a 24" will depend entirely on how high you push the FPE.... The more power, the more difference with the longer barrel....

The longer barrel, longer range rifle is a promise to myself... and will spare no useful expense. This is something I'm contemplating as more of a camp gun... with no frills whatsoever. For example... the time taken to make it possible to change calibers might be better spent elsewhere. When another receiver is $50... and has a shooting gun's worth of parts included in the price... spending much time to allow a $20 barrel change (requiring re-tuning) appeals less to me than if the gun cost me $500+.

My question is more about what kind of performance could be expected for 8 shots from a gun that has had basic hotrodding, with only 20" of barrel?
