I have enough parts to keep the five LMT and two DD guns running for the rest of my life. That's one of the perks of the CQB/MRP/MWS system ... two bolts and the barrel drops out. I have spare bolts, firing pins, trigger groups, barrels, springs, etc.
Five 556 and two 762 ARs is more than enough for us. I could get by with less, but I just really enjoy these guns so I'm keeping those pictured.
I've been doing well selling my Colts online. I need to focus on selling the BCMs, my other DD, and all of the PSA stuff I have now.
