Built pumper

[Sean]

Hi all. Is there anybody out there that sells power modified "built" pump action 1322 type of rigs?  Like the ones being built by some of the ingenious members here? Thank you for any replies.

Why not dive in and put one together yourself? These are called the "lego" guns for a reason. So much available and so easy to work on and upgrade with basic tools you probably already have.
Lots of help here to guide you through what parts are the best and how to do things.
Once you've done one you will know how to do it.
Be careful... it's very habit forming.

I have a 1322 steel breech and older 1377 with cocking knob. I don't really want to diy although it would be no problem.  I have a mechanical and machining background. I don't really want a bunch of stuff around anymore.  I am afraid I would end up,as you say, right in that rabbit hole! I might rather have someone who does it, Just do it, and simply pump it and go. Thanks for the reply.

FEAR the rabbit hole!  Smart man.  It won’t do you a lick of good though.  Five years ago I just wanted to buy a BB gun to plink with.  Now look at my collection!

If you post a WTB add in the classifieds gate I’m sure there is some one here with a nicely modified 13XX they’ed be willing to part with.

It seems Roy’s not building anymore but he may have some around:

He had 13xx guns in .177, .20, .22, and .25 a few years ago.

I wonder why he’s not doing them anymore

Thanks for the link there. It's been awhile since I looked at  doing this. I got as far as the steel breech and things came up, as they do. I'm just looking for basic power mods and replacing as many plastic pieces parts as possible. Oh! That was pretty good,right? Piston and valve port mod ,metal barrel band,12 or 14 non choke barrel,  trigger. And probably not a lot else. Unless??? HA,HA, I don't know what more really. Just simple metal stuff. 22 cal.

.... 12 or 14 non choke barrel

Just curious, why a non choke barrel?

[Sean]

I am led to believe that might slow my round down. With a LW or other quality barrel might be faster... might be. I am always open to learn as much as I can about performance.

[Sean]

Actually, always open for ANY USEFUL KNOWLEDGE!!!

I'm still pretty much a newbie but since getting my first air gun as an adult I was sucked into that rabbit hole because the one I bought needed alot of mods to make it decent. Take a look at my "Frankenpump" post that I just added if you want a bit of a laugh.   It works good though!

It was fun thou, right? That's the way my friend!

Some power up grades require modifications to the gun, like pinning the valve and a stronger pivot point, valve and barrel porting, ect. So you might end up doing the work yourself or sending the gun to someone that could that could build it for you.  What's your budget? That would be a starting point.

I'm just doing basic stuff here. I already have installed steel breech and pivot pin. Going with the RP valve combo and longer barrel I guess . Looking for a metal barrel band with sight. Only one I find is from alliance hobby. Not great reviews on him but I'll contact and try. Guess I'm doing myself!!
