How To do a trigger job on your Kel-Tec SU rifle / PLR

How to do a trigger job on the Kel-Tec SU-22. Will also be close to the same on the SU-16 and PLR guns, taking into account differences in stocks.

Apologies for the shortness of some of the scenes and captions. I had to struggle to edit this down to 10 minutes or less.

I learned how to do this by reading a thread on KTOG.org. I don't take credit for it.

Note: This is not easy and you should not attempt this unless you are very mechanically inclined.

WARNING! WARNING! WARNING!

Modifying your guns can be dangerous, and is best left to the hands of a professional. You may create an unsafe rifle, and/or void your warranty! I don't recommend that you do any of this yourself. I DO recommend that you sit at home on the porch, drink ice tea while dressed in a padded suit, and stay out of trouble.

Update:

I took out and re-filed my sear a bit more, weighed the trigger, and got it down to 3 lbs from around 9 lbs, a huge improvement. However, after about 30 rounds fired, the trigger would not reset, so I am going to bend some of the trigger spring back in closer to how it was originally.

At Step 14, when that now bent L/S hammer spring slips off and whips around a few times, it takes a bee-line for the pad on your thumb and you'll look like you played catch with a cactus.

After bending the L/S Hammer Spring back I wrapped a rubber band tight over it and around the trigger guard and it kept everything comfortably in place. When the halves come together and the pins line up in their holes, cut the band.

Under 6" groups at 200 yds, so far.

Nice video, BTW. A big help.

@BR549guy I ate up my finger too. did you do this on the SU-16? I can't imagine the 22 getting those groups at 200 yds :)

This is the greatest video of all time... Seriously though I had, previously, installed a Red Lion trigger & their video kinda sucks. Turns out I only charged the left side of the Hammer Spring instead of both. I took it to the range it was getting light strike FTFs. Figured out what the prob was, had trouble installing the hammer spring properly, searched youtube, found your video, and was able to successfully get my springs back together correctly. Thanks!!!

Thanks for the video it was very informative.

@TheHenktermaat Actually, the group was all inside 5.5" at 200 yds. I had a 3x scope and a bipod, but there was also a 10kt intermittent cross wind plus the PLR-16 had only a 9" barrel. I was still amazed.

But yeah, when that spring lets go, WHAMMO, the part of the spring that you recommended that we bend whips around and punctures your finger. Use the rubber band!

Rather than have diabetics use a lance for a blood test, they should all just do trigger jobs on Kel-Tecs. Same result. :o)

Thank you so much for this video! I just read Bam Bam's thread, and then yours, on KTOG. With the video showing the detailed step, I am now ready to go tear apart an SU-16c and try to make that trigger a lot nicer!

The safety also acts as a trigger stop. You can wrap fiberglass strands with epoxy around the trigger stop grove and turn it on a lathe to minimize the over-travel.

@Fishheadhunter I hurt my finger too :) Let me know how it goes!

@TheHenktermaat...Ok I do have 3 trigger assy. and I'll be sending 2 of them to Bill. Soooo, I may try to do one on my spare. Thanks to the video I was able to completely take apart the trigger and put in the new RL trigger. Your right it is a puzzle but wasn't that complicated until it came to loading the left side hammer spring...my finger tips hurt a bit today :)
