I picked up my two stripped lowers at fourguns in lafayette yesterday. Also grabbed two magpul trigger guards one od green and the other black. I assembled the lower for my sons birthday present last night and pinned it on the upper with a od green magpul grip and trigger guard. Safety was a little gritty so I took the grip back off and pulled the selector added two blobs of geissele purple go juice grease and it snaps back and forth perfectly now. I applied the geissele go juice oil to the trigger group. Also had to fix a couple scratches with a birchwood casey aluma black paint pin that I caused. Overall very happy with the product. I might be cussing it tomorrow when I try to install the cmmg 22lr kit. I'll report back when I get to test fire it.
Keep us posted on how the .22 conversion bolt works for you. I picked one up second hand and it's been pretty much garbage since I got it. I Haven't been able to get it to run reliably at all.
