All repeaters will be shipped with these 2 upgrades, from now on. Slip coated strikers have proven their worth.

NICE!!

So what exactly does slip coating the striker do?
I get that it slides more easily, just unsure of what the improvement is, more repeatability?

Yes. Although everything I've dropped them into gains some speed... the important things are consistency, reduced lock time, and it makes cocking these feel much smoother.

The oval tube came in... it's exactly what I hoped for!

That oval tube is awesome!! And it looks like a side by side shotgun to boot!! LOL!!

I put a TKO muzzle brake on my 1st gen .22 and I love to shoot it. Need to adjust for more shots, but waiting on a chrony. Awesome little gun shooting clovers at 35 yds 18-20 shots before it starts to string shots. My brother hinted that he'd love to have it. Gotta love this $100 gun! I like the new fill that you put on yours.

stalwart · « **Reply #386 on:** June 07, 2014, 05:02:36 AM »

Mike, it sure does. If I put a rib on it, it would look like a bolt action, tube magazine, double barrel.

Confuse everyone...

Busta, thanks. It's the set up shown in post #43, but I put a shorter Ninja fitting in as deep as possible, shortened the threaded area to need only a couple turns, and shortened the cap. A whole lotta work to lose a tiny bit of length, but I like the look. Not the most cost effective mod.

Guys, RMM's test of the speed difference between a probe style bolt, and a short flow thru with a little contouring, mimicked my results here... There wasn't enough difference to be significant.

I will be cutting the "G" slot into customs on request (holds even the longest probe bolt back for quick mag loading, and makes a great safety), but the flow thru bolt clears the mag slot if the trigger group is set right.

Something to think about, if a repeater is in your future.

Time frame?

stalwart · « **Reply #389 on:** June 09, 2014, 06:42:06 AM »

Not sure yet... hope to do a run soon, you'll know it's done when I post a pic of a pile of them.

It should be noted that both my and RMM's tests were done on air. The stubby flow thru is a bit faster, but that may not effectively apply 1 iota to CO2. The fact that the increase was minor (for the cost) at the pressure and other factors present, doesn't mean that the extra work to contour and fit the noses of the bolts was wasted.... but, it sure didn't prove cost effective under these conditions (free flowing .22s @ <2K). Unless otherwise requested, repeaters will continue to be shipped with a stout probe.

As Stalwart said we were using air. Fill was 1600 and I shot down to #1 velocity then stopped recording. As you'll note in my graphs, LOL!!, I made sure I was repeating everything to obtain as accurate results as possible. Please field questions and I will answer as best I can, but please be gentle because I'm a virgin air gunner. <GBG>

P.S. Please note on all tests the bstaley (3 - #113 70D o-rings) was installed including the WO test (It was not noted as a constant)

What would be involved to turn the repeater into a 9oz CO2 tank bulk filled gun? I don't need HPA as I don't shoot in the winter, and I can't afford it anyway. I have a 9oz on my AS2250XT and I love it.

I have 2 first gen 60c's and would like to try converting one to a repeater. I have read thru all 20 pages here and have not been able to find a "how to" section for this mod. I also noticed some mention of using a Prod mag instead. I know it's a little different than the Mrod but is there some reason it's better for the 60c? Any help would be appreciated.....By the way I never did convert either one to HP air cuz they are just too much fun and plenty of power for backyard on co2...

stalwart · « **Reply #393 on:** June 09, 2014, 06:31:34 PM »

George, there is still no better way than that shown beginning on post #104. Still not cheap, but proven.

Gmman, the "how to" situation is answered in post #154. I have a considerable investment here... you'd be surprised.

I have been looking into ways to set the shrouds up to keep the weight as low as possible. Did some research on casting the barrels into the tube... looks encouraging. Resins that can take the temps of curing the powder coat are not cheap, but are readily available. They would make for a very stiff set up, that is quite durable.

The proto shows the finished weight will be at or below that of a stock barrel... which makes me very happy. The addition of a full length air tube pulled the balance point forward about an inch... still quite nimble, but I hope to avoid shifting it further forward.

Is anyone making that pellet loader for a disco?

BNM make a repeater breech for the Disco that accepts MRod magazines.... well over $100....

While supplies last, Umarex Fusion and Gen2 60C conversion customers will have the option of purchasing all metal, sweetened trigger groups. I will be squaring the sears, and giving them a polish. I will cut these to customer's choice of where in the arc the sear's release point is, and mod to eliminate the "2 Stage" if desired.

Combined with the G slot option, you'll have the best possible safety and the best trigger.

Mike, I do have periodic episodes of unconsciousness that interfere significantly with my work. It's a bad habit I'm trying to break... with zero success.

Yarp, brew it up! I'm always ready for more.
