I have the ADM and the Area 419 QD lever. I got the Area 419 to go with their ARCA rail. The ADM works, it just doesn't engage the notches. If you have been happy with your 1913 ADM, why not just get the ADM ARCA?
Modlite PHLv2 is my favorite these days. Add mounts, switches, whatever from Unity, Arisaka, Surefire, etc. My favorite setup is the 18350 PHLv2 with a Reptilia mlok light body. No switches. Simple and effective.
You might want to order some fingerprint cards. I get mine from the ATF which are free. I use my local PD to print me, but I believe you can do it yourself??? You'll need 2 cards per lower. Good luck!
How about Proof? I just picked up a SS one and installed it last night. Going to try and shoot it today if I feel any better. Anyone have any opinions of these?
