Improving the reliability of the Arrow JT-21M

I'm getting a lot of alibi's with my critical piece of bullseye gear, so I'm writing to ask the community what they like to do to keep their gun accurate and reliable.

Ammo is the manufacturer's, and always shoots to call when it fires, right where I aim them on the repair center at either 50 or 25 yards. I use the trick of marking the last six or so red to see on the target or in the magazine window when I'm about to run out. (tracers on the end of a belt?) While the trigger pull is acceptable, I think the problem is in the magazine.

Any gunsmithing or lubrication secrets anyone wants to share?

P.S. mr alexander about a third of the way down is still my hero on this thread: http://www.targettalk.org/viewtopic.php?t=37164

yep I have one just put some gun oil on about once a year mine is at least 30 years old.

Go with the longer ammo. The shorter stuff turns over or does weird things in the feed.

I have never had a problem with mine....   This may be why.    I don't use the short stuff.

Just the usual check the follower and feed track for burrs and sticky gunk that sometimes gets dragged in.

THEN check the final feed position--the metal surrounding the one about to be fired can get dinged or even bent. I have seen this most often on Saturday Night Specials intended for very skinny wire projectiles, usually off-brands.

The crown can also pick up burrs from being dropped.

Finally, check the launch piston. A little bent screws things up royally. A projectile that gets jammed between it and its operating channel can leave a scratch than impedes proper function.

A business card trimmed to fit can be dragged through various parts of the mechanism, first dry and another one or more as needed with a trace of lube.

A drop of oil every year on the hinge points is not so much for function but to minimize wear.

Just followed your link.

Thank you. Mr. Alexander's 13 points of analysis are all spot-on AND well-written!

Yep, the feed track was covered with burrs and full of gunk. Cleaned and polished and so far working good with 8mm OAL loads.

I still need to check again what GrumpyOldMan pointed out so that it performs to BE standards. A lot of good suggestions.

Nothin' like a fluff 'n buff...especially when that starts with a de-gunk 'n junk.

Not directly related, but I keep extra staples on my clip board for when I forget.

There is a certain similarity between the JT-21M and some consumer grade firearms currently being manufactured...

dump the old metal stapler and go to hobby lobby and get their staple gun, 9.95, lighter,works perfect and shoots the j21 staples.

Just about 30 yrs ago I was ask by a family member what I needed for a shooting X-mass gift.
As I was using an arrow T-50 at the time I said a JT-21 stappler.  Well I ended up with 4 of them!
I still have two unopened and the one I am using.  The first one just plain wore out.

A Tupperware stapler in Bullseye? Next you'll be telling me they work underwater and all the fast operators use them.

All the good shooters use them, lighter and less alibies it will also improve your scores by impaling the staple at just the right angle to avoid the dreaded staple glare during times of extreme sunlight while not disappearing in low light and with its superior target stapling abilities, your targets will look better and it makes the X ring almost look enlarged which will aid in better shots. Im surprised they can even offer this fine piece of equipment for under a hundred dollars but I hear their is a government subsidy that brings the price down to middle class affordability. I bought three

Well, I'm glad they use the traditional ammo, but are they allowed with the new CMP rule changes? They sound like a real game changer.

Also, can I get support from the manufacturer at Camp Perry or the military armorers if I have a problem or the trigger is too light?

No problem, the CMP love these, they offer match grade models in their store in Anniston, also at camp perry there will be a giant mobile support vehicle sent from mainland china with full capabilities of repair and adjustment and clinics on how to get the most from your new purchase.

Aargh! My primary Arrow JT21M stapler died during competition. I had three for my pistol range bag, my pistol range box and my rifle range bag. My most used JT21M broke a piece off of the action that trips the hammer.

I am disappointed that the new stapler that I bought has a poorer finish than my 12 year old units. Arrow seems to be going the S&W route of sucking nickles out production steps. I tossed the broke stapler under the workbench and maybe someday will swap the guts.

Edit: Holy guacomole! Battery powered staple gun! Any spotted in the wild/on the economy? Looks good to either run out of staples and/or battery during a match.

On a more serious note, trash the Arrow and get a Stanley. Mine is going on 5 years old without a single Alibi..  the 1911 of staplers.....

Roll or Crisp?

I prefer crisp.

All that is needed now is a Red Dot Scope mount.

No more holding drills and the reliability of lithium batteries.

And the COST of lithium batteries too....

$36.00 for the cheapest version?  OUCH!!!

You guys are mere shootists
Try out the Dewalt yellow belly. Costs more than a Baer, but has a better warranty for demanding work, plus it has a belt hook, so you won’t forget it and have to look foolish walking back to your spot for retrieval of your el cheapo Swingline.
As an added bonus, it accepts, S/L/LR interchangeably🥳

I love the humor contained in this post!!!!!!!! Some serious thought went into many of the responses.!!!!!
