That is one build you can be VERY proud of, Outstanding and I love the Blue/Silver Grey colors.  8)


Very impressive build,
I would love to get you, Alan, Scott ,Lloyd and some others all under one roof of a fully equipped shop,
turn you guys lose and see what would happen, to include a Lab Radar set up for 100+ yds etc.  ;)

I do believe that the AR scene would be turned upside down with the results etc.  8)

You guys rock........Thank you for all you have done for, for us following behind.



Thank you,
I am following along behind you, LOL.  ;)

I do have a question/concern,
When making the stem, do you have any problem with the stem sliding up/down the end of the stem,
I relies that you press the stem into the Peep head etc, this is enough to hold the head securely on the stem?

Ask Bob / Re: Correct thread sized tap?

Thanks Guys, Great info.

The reason for my question was, I have numerous adapters, from the JT 88g type to Co2/Hpa standard tank/bottles sizes,
they run from .800" (smallest diameter) to the large end at .829" dia, most run .820"/.825" size bracket,diameter across the threads tops.

I have to make a couple Co2 transfer adapters/couplers, 1-1/4" hex alum, going to transfer some of those 88g Co2 cyl into a larger tank, for less messing around etc.

I am running a 1x9" twist in my 17 wildcats cases, from 2.5grs to 14grs case capacity,
and all the rifles/pistols I have shoot all bullet weights from 12 thru 25gr, very accurate.

Where you are going the air side, you should be able to find a .172 bbl fairly easy,
look for 17 cal bbls from the Ruger series of PB rifles, will have to remove the RF chamber,
and depending on how the bullet drop from the mold, you can size them to what you need,
using soft pure lead etc.

What would be the correct size of tap/die for the ASA threads of a standard air tank?

I have been told several sizes, like 7/8"x14 tpi, 13/16" x 14 ttpi etc,
the thread measurements of the type of threads I have are, .623 to .628 dia x 14 tpi.

Thank you,


Thank you for ALL you have done for ALL of us, You have set the bar very high,
very few can even see to that level.

May you and yours have a very Happy and Merry Holidays,

Your friend,

Thanks Ricky

The hammer spring would not strike the valve stem, it is so light and lost compression etc.
Mine also has a spacer ring at the back of the main hammer spring,
even with this spacer this spring had NO strength to move the bolt etc.

The 17 cal bolt flopped around during to movement, enough to hit the end of the chamber etc, when cycled,
so I have a new 22 cal bolt coning for it, and will fit to the action etc,
this AR started life as a 22 cal, then was changed to 17 cal, by whom is a ?.

IMHO, the sealing for the valve stem is kinda funky, just that 1 little "O" ring?
There has to be a better way of sealing, just have to figure it out etc.

Did you use the Hammerli slide on scope base for the rings, for scope mounting?

I finally got the cylinder out, yes, it still pressure in it, had to use a small strap wrench, was jammed tight......
finally got the action opened, and found at least 3 pellets jammed inside, and 2 in the bbl.  :o

Found a part floating around inside also, get it back in it's proper place,
have to fix the stock bolt holes, all mushed out, easy fix,
bolt handle bent, will straighten that out,
bolt nose slightly bent .

Waiting for the new parts to get here, "O" rings, springs, ball bearing, etc
hammer spring just slid back and forth, over 1/8" play, etc.

I am a Happy camper, now........ just waiting for the pony express rider  :)

Thanks guys,

Yes, it is a air rifle, Hammerli 850 Airmag. 17 cal.

So far, it is just sitting in the corner, untouched, I have attempting to remove the cylinder,
IMHO, it appears to be locked in, just like my QB79, when a live cylinder is in installed.

I know that you should NOT remove the action from the stock, with a live cyl installed, in the QB 79 etc.

Thanks Ricky, I'll check that info out.

I can't seem to find the correct answer to my problem,
A little history,

The neighbor HAD a Ham 850, 17 caliber AR, OEM stock, (He bought it new, 7+ yrs ago).
It was sitting in the corner of his shop,
I really don't care for this caliber, but will try it out, I prefer 22 cal.
He made the comment that, "It's yours, for $100", (he knows, I am into guns etc). LOL
He also told me the bolt didn't work right, before I bought it. He stated, that he has shot it less than 1 cylinder thru it,
and then it locked up, bolt don't or won't close, etc.  :o (bolt moves a little back and forth).

So, being the Idiot that can't resist a gun, It followed me home and put into the "needs work rack",
right now it is 5* inside the unheated shop, too COLD for me be inside for very long..

Being new to AR arena, and knowing nothing about Ham 850 AR, 17 cal etc,
I have 50+ 88/90g cylinders, so that end is taken care of etc.
I'll have to get a couple of mags, it didn't come with any, the owner that he has a couple mags, ammo etc, just has to find it all.

I have not had much luck searching the forums so far, on this make and model etc.

Since, I can not get the bolt to operate in the full range, at this time I am unsure what's in the bbl,
It feels like something is jammed in or around the bolt, the bolt only moves around 1/4" or so.

Being a new (to me rifle), I will completely dismantle, check and clean/lube the required parts,
along with adjusting the trigger to suit me, before I shoot it.

Question for the guys that own or have used a Ham 850 Mag AR.

This AR has a cyl installed and can't be turned etc, so I believe that that there is pressure still present,
I can NOT operate the bolt more than 1/4", to confirm this or deny, or see if this AR has a pellet in the chamber etc,
and the safety dose not feel like it's working right.

Can I safety remove/dismantle this AR, to find out if pressure is still present?

I know nothing about this AR and IT'S inter workings etc.
I finally found a diagram of it's internal workings etc, but no other info was given.

I don't need a Kaboom......


Still waiting, my 79 is drooling all over the place...... 8)

With a SSG and your valve, it should be the ultimate tuners delight, to get the most from AR's,
for us new ones following along and learning.

Thank you, Travis
