Another one succumbs to the .177 bottle build -

[SteveV]

Need to get another Tom West stock for this little carbine, but other than that, no complaints.

Of the pellets I have on hand, it prefers H&N FT 8.64 gr

Shooting them in the low 900's for close to 17 fpe - does the trick -

From not quite 40 yards -

Any availability on QB78 regulated Bottle conversions that you know of?

 

[SteveV]

Maybe Mountainair Custom Airguns?

I have one of the QB 78S that you posted the bargain link on, got it this time last year in fact. Bought a bottle adapter from Archer Airguns, but it won't work lol!, wrong dimensions/spacing, not sure of what version of the QB the adapter was made to work with - would you have an idea?

Nice shot!

I cobbled together a similar build a few years ago. Started with a 2240 pistol and converted it to .177. Used a QB tank block, added a telescoping buttstock so the kids can use it too. Pretty satisfying build.

O’doyle, a Gauntlet tank block is the best buy for QB78 conversions but Umarex has been out of stock for a while.

Archer wants $37 for the QB79 version which is absurd, plus the location of the retention screws is not as good in terms of safety margin.

Cross posting THIS thread onto the other heads up cheap QB78A thread for those interested on HPA conversion thanks!

HOLD ON GANG!!!

The two of you aren't quite done solving QB issues -

This is a pic of my QB 78S and my Archer tank block adapter -

WTF?

 

[Odoyle]

LOOKS LIKE YOU GOT SOME SERIOUS BREECH SHIMMING TO DO! Wonder how the bolts gonna cock the hammer though?

 

[SteveV]

I ain't shimming squat - this is the wrong part, or there isn't one made for this version, I'm just not QB hip enough to know -

Maybe this is best answered by Mr. Stephen Archer.

No worries, just a pellet gun lol -

BUT - if anyone cares to enlighten me, I'm all ears -

 

[nervoustrig]

That’s a different adapter. The one you’d need for a bottle conversion is the QB79 block shown below or the Gauntlet version (better).

[SteveV]

It's the one Archer Airguns sold as a QB bottle adapter -

Yep, the one in your pic is the right one. Wo to me lol

Steve, been to long.

You might want to call umarex (times change eh?) for a gauntlet drop down. Think crosman prices! Naturally not for everyone but you'll be able to cut & drill your tube also it is a better design than say a qb79. Did I mention price? Found this link on this forum somewhere, you'll want the 6-1.

Beautiful shot, beautiful gun! 

 

[SteveV]

Good morning John -

Turned off the 'puter before I saw your reply -

Yeah, looks like I could have saved some $ if I had purchased the drop blocks elsewhere, but we live & learn -

Thanks for the link, sent you a PM, hope all is well on your end - will talk this evening.

Beautiful shot, beautiful gun! 

Thank you Mr. Bulk!
