Description

The TX22 Metal Striker Insert Upgrade is a direct-fit steel replacement built for shooters who need dependable function, especially when running an FRT or heavier rearward mass. Machined from O1 tool steel, heat-treated, and black-oxide finished, this insert resists wear and maintains consistent performance under demanding use. It also adds rear weight to help with suppressed setups, though total balance will vary by suppressor (you may still need an optic). Compatible with both Gen 1 and Gen 2 TX22 models.

Specs

• CNC-machined billet O1 tool steel
• Fully heat-treated
• Black oxide finish
• Compatible with Gen 1 and Gen 2 TX22
• Designed and made in the USA

    works perfectly. If you're gonna frt the tx22, you really need a metal wear surface in the upper.

    The cut out for the plate with the little spring (having a brain fart and can remember the name of it) it a bit too tight. Am in the process of shaving off some material little by little till the tolerance is right, but other than that it’s pretty straight forward and neat.
