QB co2 posts

So it's similar to a gauntlet inside, they have a spacer in between the end cap and spring guide as well. It's just shorter than that. I haven't torn my gauntlet down past that point yet but need to. Feel a good blast of air coming from somewhere around the breech and for having it shimmed pretty good and also a 2100 psi regulator it's only getting 910 fps with 25.4s, should be in the 950s or better I woukdve thought.

Took a QB 79 out of the Plastic stock, and put it in a 1400 stock, had to inlet for the barrel band. The same stock that the 1085 repeater has.

That looks slick James! I like the sporter style fore grip cut and the raised comb. I had a 262 stock I modded and put on a 2240 with a safepac.

I thought the 1400 was a pumper... so many crosman numbers it's hard to remember what was what!

yes it was a pumper, the stock was too weak to continue life as a pumper. I screwed the pump arm to the stock using some metal straps.

Nice job James., Did a good job with that,  it looks good. The single shot QB works well enough with standard stocks….the repeater version needs more cheek.

Likely tried the 1085 in several QB stocks...some inletted for the square bottom barrel band, some with it just ahead of the stock.  'Square" isn't a hard inletting shape to manage.

There was enough wood in the skinny 78S fore end to manage the insetting.  ALL the QB single shot stocks end up with a real low comb when used with the repeater (so does it’s issue plastic stock)...really need to raise the cheek...a lot...with all of the stocks.

A few good things about the 1085 repeater for someone who likes to “tinker toy”.

The 1085 tube is exactly like a  QB78 tube (has the pin slots even though the 1085 doesn’t need the 2nd slot).  It’s also just like the QB79 tube. The cock on opening parts will fit into any QB78 and work.

So if you had a QB79 tube, a long 78 tube converted to tanker, or even the issue 1085 tube converted to tanker….would accept the cock on opening parts and repeater receiver/upper.


WHY?..Having the barrel so high would allow the HPA tanks to clear the barrel as you screw them on or off.

IF you add an in-line on/off between the tank and the tank block, can just turn it to off...a few shots to empty the rifle...and the tank unscrews easy with no presure in the tube.  Put on a new (full) tank, switch to a co2 tank, or just work on the rifle with the tank off but still holding air.

(If China is listening….make the repeater on a QB79 tube….it will all fit and work.  They would just have to inlet the short wood stock for the square barrel band base.)

Meanwhile, having a fun with the 15.6foot pound .25 co2…..way long, but fun anyway.

My “queen” of back yard ratters was a .25 springer that only manages 14 foot pounds.  Perfect for back yard ratting. Get that immediate “thump” of a .25 and it's only 25 yards to where the rats had been a problem.

But my current health concerns/treatments make cocking a springer (including a gas ram) difficult.  The too long co2 QB ,25 is going to take over that job.

[BC81]

I'm not a springer guy but that one looks really nice. Not super long like alot of them.

What brand is that Robert?

[Ribbonstone]

BSA Supersport SE GRT….disontinued.

Takes a lot of practice/adaptation to what a springer wants…currently, I’ve lost that….but they can shoot pretty well.

“Nothing” in PCP terms, this cluster of +1/2” at .25 yards would be pretty poor for a PCP ((back when I was “on my game” with springers.  Can’t do it now.

Cheapest possible PCP (the old $100 FDPCP) in comparison:

 BUT….you do realize, even with a larg difference in group size and energy...a rat would be equally dead.

[BC81]

I love the targets man!

It is a nice looking springer for sure. I never had any good quality ones to justify liking them. Got my hands on a pcp and never turned back! Only have the one qb78 and it'll most likely be HPA soon, but you already knew that lol.

[Ribbonstone]

Easy guess….6 of them is likely too many.  3 HPA and 3 Co2.

Got rid of the plastic stock on the .25 and thought I’d take a current QB group picture.

L to R: .177, .177, .22, .25, .20, and .177
