I had some cool surplus parts lying around, and got into an inexpensive Troy Delta. The problem was I had too many 14.5" 5.56 ARs to justify another one. So, on Black Friday, I copped a CMMG conversion kit and  .22lr M4 barrel cheap, and a BoreBuddy reliability kit-and built out an AFSOC M4/Garand Thumb's Work Gun for high volume training and smoking varmints. I'm really happy with how it's going so far.

I have a FN Collectors M4 lower sitting in a box to switch over to. I still need a sling setup (IWC mount in slot sling mount?), light/light mount, and a rimfire suppressor that doesn't look tacky. I'm also going to hit the Black Dog magazines with some dry film lube, and make some magpulls out of 550 cord and 100mph tape, to make them look more GI-ish and less like toy rimfire mags.


Build as it stands:
Demco dogbone upper
Demco contract CH
CMMG .22lr BCG
CMMG 16" M4 profile barrel
Borebuddy rifle reliability kit and silent collar
Surplus A2 FH
Troy Delta handguard and AFG

FN lower
Schmid Tool GI Nuts LPK
Surplus A2 grip (I have a Tangodown somewhere I may swap in)
Colt overrun buffer system
Surplus Vltor clubfoot

PST2 1-6/ADM Recon mount
KAC 300m rear

Very cool!  Do you find the A2 front sight interferes with your sight picture through the scope?

It cowitnesses on 1x, not an issue. On 6x it's not visible in the sight picture. The objective collects light from around the front sight post and you see everything behind it.
