Tm22 Light Strikes

[u/Rubiconcross45]

I recently purchased an 18inch tm22 pro. But I’ve been having a hell of a time with it.

First time shooting I was getting a light strike every other round probably 50% failure rate.

I broke it down fully cleaned and oiled everything and took it back out to the range and I’ve found I’m still getting light strikes maybe 20% of the time which is better than 50%. I inquired about warranty service but that’s shipping on my own time and quite a long turnaround through SFRC.

Does anyone have any suggestions or experience with this? I’ve thought about cutting maybe a coil or 2 off the firing spin spring to make it easier to move?

My 16" TM22 Pro was also doing light strikes. It turned out that the bolt guide rod and spring were out of true because of a loose receiver bolt on the top-rear of the receiver. This allowed the rear of the guide rod to rise perhaps a half millimeter. This caused the bolt to tilt ever-so-slightly downwards when it would make battery with the chamber.

After a frustrating wave of light strikes, I disassembled the receiver by removing the top pic rail cover, removed the guide rod/spring and bolt, cleaned and lubed the bolt block edges where it touches the receiver, and reassembled, making extra sure to mount the bolt guide rod/spring securely into its notches, and that the receiver cover/pic rail are securely tightened down over top.

Voila. The TM22 Pro now runs like a pro.

p.s. I use CCI mini-mag round nose, Aguila Super Velocity round nose, and Eley Force round nose. All of these run reliably in both my 16" and 18" TM22 Pro's.

I do get occasional cycling issues when I use hollow point versions of the above or any ammunition. Methinks the hollow point gets hung up on my feed ramp. (Perhaps some feed ramp polishing with a Qtip and some Autosol polish will make my TM22's like hollow points more)

I do get failures to feed with CCI Stingers and their slightly-longer cartridge cases.
