Firearm attachments part 2: The fun attachment for AR

I was at a good friends farm recently and we were shooting and having a great time. Someone at the farm then reached into his AR (what I refer to as Accesorizable Rifle) case and pulled out what appeared to all present as an M4. He inserted a magazine and as I was looking away he pulled the trigger. The sound immediately yanked my head around. I had not heard that exact sound in over 26 years. It was the exact sound made by my Squires Bingham M16 look-alike rifle I had purchased when I was 16. I unconditionally had to have whatever that was in the shooters hand. It was a CMMG 22lr complete upper. I took it home that day and since then I have fired over 4000 rounds of bulk pack 22 ammo. I do not use Remington bulk pack as a rule due to it not working well in my semi- autos in the past. My CMMG upper has served me well. To date with 8 boxes of 555 Winchester 22lr. I have had 3 misfires with good primer strikes. No failures to feed and no failures to extract. I have since carried them on my table at gun shows. They work and shooting 22lr through an AR 22 complete upper is like eating 5 calorie hot wings. ... Guilt Free
