TM22 Trigger not resetting

[newsharpshooter]

Hey all,
I took my new TM22 Pro out, tired about 100rounds through it. CCI Minimag and CCI standard.
The bolt would cycle and chamber a new round, but the trigger wouldn't reset and I'd have to cycle it manually.
I cleaned it and oiled it prior to taking it out.
Is this a gunsmith issue?
No I cannot return it/exchange it.
Thanks!

I know two people owning a TM22, both had exactly the same issue with their rifles.. Rumor has it, this issue goes away after sending enough rounds through. Enough is at least 1000 rounds... can be more

Make sure to check the top of your TM22 receiver and tighten those two vertical Allen bolts in the picatinny rail. They are critical for the rifle functioning.

One of my two TM22's had a loose bolt at the top rear. It allowed the bolt assembly guide rod to ride up by a millimeter, which was enough to throw it out of true. The bolt would not reset the trigger perhaps every third round, or it would fail to strip the next round from the top of the magazine.

Once I discovered this loose receiver bolt, I opened up the rifle, reseated the bolt guide rod, closed the rifle up, and tightened those receiver bolts snugly.

Voila! The rifle runs smooth as butter now with CCI mini mag ammo, Federal champion ammo, and Aguila 1200fps ammo.
