Why are SL68ii's so fun?

[Bubkat]

A bit off topic, but I ordered SHP tank to remedy low velocity. I see that the ninja shp tanks come set at 1100; do you think my velocity will be too high at that output?

Horseshit, ZoS, and you should know better: pressure is pressure. Get the right pressure with either gas and be done with it. HPA was very much a thing in '95. My Pro Lite gets 300 fps on CO2 or HPA. It couldn't care less what was making that pressure.

I'm not exactly sure what release mine is, it does have auto trigger tho, I remember hearing only the releases have that

[BenoitOWN]

Both for the re-release but even then they are getting ‘old’(2009?) but compare 25+years old that will bring a toll on springs.

SL68II are so fun because there compact light and bullet prof reliable. Just used mine for fist time in a couple years now and had a blast.

And as for the velocity mine has No issue shooting 280fps on HPA with the .680 palmers barrel.

Now mine is also the rereleased model not sure if that has anything to do with it or if it’s just down to the much tighter bore barrel.

I've read on old forums about guys swapping to a lighter upgraded "cocker" spring in order to increase velocity when using HPA. Anyone go this route?

For the valvespring? Didn't try it.
My first thought was to use a stronger mainspring but as others pointed out it's an odd size- anything you use in there has to be exactly the right diameter to fit between the hammer and bolt- I've got a ton of cocker and Nelson springs in my parts bin and nothing I have fit right except the springs that came in the guns- that's why I went with shimming them rather than replacing them.

I can't recall whether the valvespring was also an odd size.

They weren’t designed pretty much for CO2, they were designed with no regard for any other gas. HPA tanks didn’t exist at all in 1995 or whenever it was. HPA and CO2 are often not a direct swap. He probably needs springs or a tank that will make slightly more pressure than 800psi.

I fixed up a bunch of SL-68 IIs for a local field by shimming their mainsprings. If I remember correctly I was making the shims by using my dremel to cut little rings off of a 1/2" brass tube (I THINK it was 1/2" but I'm not positive) , so that I'd have different sizes for tuning. Once properly shimmed and given nail polish detents in their barrels (you paint the detent stripes a little ways into the barrel to give the bolt O-ring room to protrude) they had no trouble shooting modern paint at 280fps reliably.

Oh I've been thinking of swapping it to stock class or at least 12 grams for a little while, it honestly seems like it would pull it's weight like that perfectly fine

While I own an old skool SL-68 II, and agree that they are fun... I just recently did a 1v1 with PGPs a couple of weeks ago. It was silly cheap fun! On top of that, we did it on a hyperball field. 230fps bunkering was smiles for miles! I highly suggest!

I would personally use CO2, if you can still get fills in your area. This gun wasn't meant for HPA, which isn't to say that it won't work, but it was designed for a higher pressure and this is gonna be your "lowest hanging fruit" solution in terms of cost and effectiveness. $25 bucks for a JT 9oz at Walmart and I do think you'll have a nice light playable setup without much fuss
As for why cheap fun guns are so great, I think it's just the realization that you don't need to drop $1300 on the latest Dye or PE to have a solid, playable gun and have fun with it. Plus the variety. Everybody needs a couple for the gearbag

Ok so the bolt dose need modification Colin takes about .001 off the bolt, makes a longer pump arm and then prints a sleeve to take the slop out of the pump handle.

Colin@deadlywind.com Has modified modified a bunch of these. Shoot him an email he will get you all hooked up and that thing shooting great. It’s not as expensive as you would think and it really makes them shoot nice.

[Chuck E Ducky]

Well it’s not mine, I just modified it for him I chopped the feed neck filled it opened up the side to drop First strike rounds into it then painted it all in so it looked cool. I left the dove tail on the top so he could attach optics on it if he wanted. But it actually didn’t need em. It came out cool I’m going to get him to send me pictures of it. I might have some pictures of it on my old phone somewhere.
