1720 T modifications for Field Target......any suggestions?

Nation,

I'm not much of a Pistol guy, but this is something I need to explore. 

Dug out and dusted off my Crosman 1720 T, plopped a UTG 2-7x Pistol scope (long eye relief, because I shoot hands only) on top. I'm getting a decent number of shots, shooting an H&N Field Target Trophy at 8.64 grains, at about 650 FPS, and that's about all I can get out of it velocity wise. I'll have to look into my records on how I got it up short of 12 ft. Lbs. I plan on putting a Huma regulator in it over the next few days, and I'll probably leave the gauge block out in order to get a few more shots.

I began shooting it, and was relatively pleased with it at Field Target distance (35 yards and in), and the accuracy that it had. In just plinking around with it out to 55 yds+, I was amazed at the incredible accuracy that this thing has. If I would have to make a dumb statement, I would say that it was hands down more accurate than ANY of my high end Field Target rifles. And it was a little bit windy as well. I was just truly amazed.

My question(s) are......

What upgrades can I do to it, in order to use it for Field Target rifle competition? This one I'm going to keep in it's present form, no need to change anything out on it (except for what I'm going to do to get it to 11.5 ft Lbs). I've got the trigger group that comes with it, and its pretty sweet.

I was thinking ( other than tuning parts and regulator to get it to 12 ft. Lbs) on what stock options are out there? I do know that some people have modified Challenger stocks to put them in, I wouldn't be objected to that, as I do have a Challenger, and feel very comfortable with it. Is there anywhere where I can get an extended air tube? I understand that it's the same size as the Discovery and the Challenger, and would like the increased shot count. 

I will acquire another 1720 T for this project, and keep my current one for Pistol Field Target.

Any and all ideas, recommendations, thoughts and guidance will be greatly appreciated. As I witnessed today in it's accuracy, its something that I cannot ignore.

Thanks,

Tom,

I have my 1720T set up for FT.

But, I have always said my most accurate air rifle was my 1720T..

I put a standard PRod TP in.

I replaced the spring with .300 x .041 x 1 1/2” spring.

4 o-ring bStaley

3-12X Scope

I shoot 7.33 at 842fps...

When I run out of the 7.33 I will use the 10.34 JSB I use in the Marauder at 12fpe.

Good luck.

My most accurate combo with the 1720 has a reg, mine is a Lane reg, came with the pistol used and JSB Heavies. It is my wife's FT pistol now. 

27 gram custom hammer, reg, and a .041 spring. 

I'm getting 50 shots with Jsb 10.34 at 710fps, factory tube. It is a great little gun and is extremely accurate. 

I recently printed a new stock for her, and it turned out great.

If you're looking for a stock the Challenger is great, but I also think the Beeman AR2078A stock is a great one for the 1720. The picture isn't mine, I got it from HAM Hard Air Mag.

Guys,

Thanks for your responses.

Skip, I might just leave my trigger alone, it's pretty sweet as it is, and I have extra trigger groups. I don't think I can get it any better than what it is.

Frank, that's a pretty sweet setup, I think all I have to do is swap out the transfer port to get just under 12 ft. Lbs. I'm looking at leaving my Pistol alone, and am looking for a stock option to use in WFTF PCP class in the rifle division. I'll buy another 1720T to use in it.

That being said, Cameron has a sweet setup as well, and that rifle at the bottom is actually Greg Shirhalls gun from a few years back. He already contacted me in guidance for this project. That's along the lines that I'm looking at, that's why I was looking for tube extensions. This way, there will be less modifications/machining if I were to use a bottle, which I do have.

Thanks guys, keep the ideas coming, between the great ideas you guys have, and the help of others, I'll be able to figure out something.

I'm considering this gun for my 5 year old, took him with me to the field target match this weekend and he, surprisingly, took a liking to knocking down targets. He was using a Brocock that was entirely too big for him. 

I've seen people shorten the plastic crosman stocks and I'm thinking along those lines....

The big issue here is the 12fpe of the 1720. Can it be made to shoot up around 17-19.5fpe? Understanding that it'd have short shot counts. 

I understand many of you are hard core 12fpe guys, practicing for wftf worlds here in the states and all, but that just seems cruel to get a kid an airgun, make it fit him, and then make him shoot at 12fpe while I'm up there around 19.5fpe right next to him. Id like to set the hook a little deeper, not dissuade him from enjoying it. 
 
Franklink,

I'm not sure if a 1720T can physically push the volume of air needed for 17-19 ft. Lbs, I don't think the smaller diameter valve can handle the volume. At very least, maybe by installing a Discovery valve, that might be able to get you to that power level, but will not yield much of a shot count with an unregulated gun. Even regulated, given the small diameter and length of the air tube, shot count would be really low.

As for your 5 year old and shooting, don't rule out a 12 ft.lb gun. Power doesn't always mean accuracy, I've seen many 12 ft lb shooters beat the pants off of high power guys. In my mind, if he enjoys physically shooting with you, it might be beneficial to use a lower power level gun, just for the reason of higher shot count and more range time, than stopping to fill it every 6-8 shots. Also, if he learns how to shoot a lower power rig effectively, it will make him a better shooter in the long run, and when the time comes for him to graduate to a higher power setup, he'll already be a seasoned, disciplined shooter with a good base of fundamentals. I can safely say, even with my 1720T shooting at 11 ft.lb, it's so accurate, I wouldn't hesitate to use it for longer rifle distances, thus the original purpose of my post. If anything, I would not think it would prevent him from enjoying it, rather a good, solid place to start.

Thanks for your thoughts Tom. 

I posed a similar question (about a good youth gun with a short lop for field target) on a different forum and a handful are saying go with the 1720, some are saying convert a Disco that I have (swap to .177, Marauder gen 1 trigger and spacer, LW barrel from Challenger if crosman has any, chop the stock, etc), and the third suggestion was the cz200. 

I was surprised to learn the red laminate cz200 can be had for roughly the cost of the 1720. Although, with the cz200 I'd still need to chop the stock to get the length of pull right. I think itd just feel wrong to cut up that pretty of a stock. 

So, back to the 1720...... seems like I remember that you've got some Steyrs? Am I understanding you correctly that the 1720 is giving your Steyrs a run for their money?

Cole,

Yes. This was the origin of my first post. I shot my 1720T at 55 yds, and with only a 7 power pistol scope on it, I couldn't really zoom in with a higher power scope, as I can with my regular Field Target rigs. I'm competing at Crosman this weekend, and they give us great deals on stuff, and a 1720T is usually on it. I'm getting another one to turn into a rifle for WFTF. Sounds insane, but it is a stupid nail driver.

I just posted a new video on my channel, and I take all of my WFTF rigs at 12 ft.lbs, in the wind, and I was amazed what they did with JSB heavies.

I would look at several options.... the CZ 200, 1720T, Discovery, and some others that I cannot recall at the moment. As you said above, it would be a sin to slice up a stock like that, and I agree. The CZ 200 has my eye as well, but I already have too much crap, and I'll need to thin the herd. There is no foul if you do get a CZ 200, and put your own stock on it, saving the OEM stock for when junior gets bigger. Not a bad option.

There's definitely a few ways you can go with this, as I said, don't be afraid to put a lower powered rig in his hands, there's no shame in that.

If you need more guidance, don't hesitate to PM me, or start another thread. I'll be glad to give you all the insight I have.
