Numrich has the entire striker assembly of which the cocking piece is one part. I bought the complete 591 striker assembly for $38.00. A lot more expensive than the cocking piece which sells for $6.60. Only no one has the cocking piece in stock. Since my 591 is my daily varmint rifle, I am glad to get in back into service when the parts arrive from Numrich.

I bought my 5mm as a 15 year old in 1972 new at a local Coast to Coast hardware store in Iowa and for Christmas my Dad bought the Weaver cross dot scope that I put back on it. I used it for several years and was a crack shot with it! Big feral cats, opossums, gophers, raccoon, fox, dimes and pennies you name it! Rabbits were especially fun.
Well a year ago I found out about the new ammo being made and bought some and after 40 years it's back! So exciting to shoot this again. I stumbled on this forum and I am glad there is a following. I had no idea the prices for these are so high, it just sat in my case for literally 40 years and I just assumed it was a boat anchor.. I do have a box of original ammo that I never did shoot that probably 35 years old..!

After stoning the sear engagement surfaces & getting the pull wieght down to 4 1/2#, I did some shopping @ the local (old fashioned) hardware store.
I couldn't find the exact diameter spring as the original. After rummaging through some drawers in a back room, I found a spring that, although slightly bigger in diameter, would fit within the trigger housing. We picked through the springs & found 2 that were ever so slightly smaller in diameter than the rest.
I bought 2 @ $1.09 ea & with some 4-40 screws, a 4-40 tap & a #43 drill bit, my total bill came to just over $7 including tax.
Here is a picture of the spring as I bought it on the left, the OEM spring center & the spring length that resulted from trial & error trimming/fitting/trying on the right.
I widened the notch in the sear ever so slightly to the rear to allow the new spring to snap into the notch & stay there.
After studying the design of the trigger, I came to the conclusion that a sear engagment adjustment would be problematic. The safety does not block the sear, it blocks the trigger. I did not feel comfortable tampering W/that sort of arrangment. There was no slack between the trigger & safety in this particular trigger assembly & the sear engagment was not very deep anyway. I could never detect any creep in the break so I decided to forego adding a sear engagement adjustment.
I did however, drill & tap the trigger housing @ the lower front for an over-travel adjustment screw. The location of the bolt stop requires that the screw be located very low in the front of the housing. The loaction is very close to the pivot point of the trigger. I decided to angle the over-travel adjusting srew upward to allow it to engage the trigger further above the pivot point & also to allow clearance for the bolt stop.
I trimmed a 4-40 socket head screw to length & pointed the end so that the threads would not become damaged from contact W/the trigger.
The screw clears the bolt stop in both the up & down positions.
It can also be accessed W/O removing the action from the stock by removing the trigger guard.
So now let's discuss the working of the spring length & sear engagement surfaces.
Earlier I had achieved a 4 1/2# break by merely stoning/polishing the sear engagement surfaces.
Even after trimming the new spring several times to a length/installed tension that I felt was minimal for safe operation, I had a 3 1/2# trigger break. Still above the desired 2 1/2 -3# range. Just for kicks I re-installed the OEM spring. That gave me a 4# break.
Reducing the spring tension further was not a safe option & it seemed to not be reducing the break weight proportionately. I decided that stoning the angle of the top of the trigger sear engagment surface was the key to a lighter break wieght,
I ever so slightly stoned the sear engagment surface on the top of the triggger in a downward direction, perhaps 1* or 2* @ most. After several strokes, I re-assembled the trigger in the housing W/the new shortened spring & tried the scale on the break. W/O the safety installed & the action out of the stock, I got a consistant trigger break @ 2 1/2#.
Time to assemble the whole thing & give it a try. I adjusted the over-travel screw for zero overtravel & used "wicking" grade Loc-tite on the threads.
As I have experienced in the past W/other rifles, when the entire trigger, safety is assembled & the action tightened down into the stock, the trigger break weight went up slightly.
After spraying some G-56 lube down into the sear engagement area I now have a consistant, reliable beak @ 2 3/4# W/zero perceived over-travel. Dropping the rifle on the butt when cocked W/the safety off did not result in the striker falling. I did this several times from as high as 1'. I also slammed the bolt shut, pulled the trigger W/the safety on & them switched it off. I did these tests several times & never once did the striker fall W/O an intensional trigger pull W/the safety off.
I'm quite pleased W/a 2 3/4# trigger break. All of my hunting rifles have 2 1/2# to 3# triggers so I will be able to work W/that.
It is a far cry from the 5 1/2# pull I started with this morning.
I'm very pleased W/may 1st DIY CF rifle trigger job.

I just finished off a sweltering week of PD shooting that involved the T/C 5mm when applicable. It was fantastic. Three misses and 11 dogs total. (No pictures, unfortunately) The last dog of the day was in 102 degree heat at 156 yards using the Varmint load. He was half obscured by the waving grass and I shot him standing with the rifle foreend resting on a camera tripod. At the shot I could see the spray of blood and saw him flip backwards into the hole. My hunting partners saw it as well and were mightily impressed. I got three today: 40 yard head shot, a 100 yard shoulder shot, and the aforementioned 156 yarder. Oddly, the guys I was shooting with were using very accurate 22WMR and 17HMR rifles. They each hit an equal number of dogs but the 22WMR 40 grain killed them better. Neither of them held a candle to the Five, though. ~AMMOe

Here are some photos
This magazine is not finished
It is hard to hold the rifle work the bolt and take photos at the same time.

They will be anodized black when finished
We made them a little deeper so they can hold a little longer cartridge
They will hold 5 rounds
We don't have a prioce yet because we are still refining the machining and the finish costs
We will bring out a 100 the first major release which should be by the end of July
You will read about them here on the 5MM Forum first.
They are made on CNC milling machines.
