What lower did you use....I am looking for one as close as possible to the original
I used a Colt Made In Canada A2 lower. I pulled it off of my dissipater and put it on the 733 since the color matched a lot better. The A2 lower would be period correct as well.
Nice catch Leg! I had that in mind since the 607 and XM builds I have going need the lugs taken off. Well I guess on the XM some have them milled off and some don't.
I will swivel the mount but I couldn't do it before because of the tailcap on the 660. The 6P that's on its way with a remote pressure switch will be a lot nicer setup and more correct. The mount came off of the Surefire 660 that I bought off of Ebay.
I'll post new pics when its done. Hopefully the XM will be completed by then as well as I'm still waiting on the 607 buttstock and handguard cap to finish the 607. That is still months away.
