    RMSc adapter plate for TX22 Competition?

    Posted by Les Schultz on 17th Sep 2023

    I was real excited about this. Shipping was quick. Upon receipt, I quickly noticed the lack of recoil lugs - the main difference in optic footprints and the reason adapter plates are made. I should have looked closer at the picture. Well I have it now and mounted it. Haven’t shot the TX since putting it on, but will see if it loosens over the next few range visits. If it holds fast, then I’ll mount the optic and see if it stays in place. If over the course of a few range trips it holds, I’ll change my rating. The “composite” material is a lot softer than I expected. It’s not a laminated composite, so I’d say it’s a hard plastic. We’ll see. Time will tell.

    Perfect for RMSC RDS

    Posted by Meech on 31st Aug 2023

    Nice clean fit on TX22 Comp for the smaller RDS like Romeo Zero and accommodates shroud. Do not over torque while securing this plate to barrel. The plastic material is soft. Recommend not to exceed 15 in/lbs.

    TX22 Competition Mounting Plate for RMSC

    Posted by Michael A on 10th Aug 2023

    The Reflex Sight adapters that came with the TX22 Competition Conversion Kit did not accommodate the Holosun 507K. LAKELINE in for the save. Perfect fit.

    Works great!

    I was a little skeptical about this being plastic but the plastic is a very high quality. It fits the pistol well and looks better in my opinion.
