Great price, Super fast shipping.
This was an upgrade I had in mind for an A2 I had bought back in the hoary days of Bill Clinton and the AWB of 1994. I had an upgrade to a flattop upper in mind for quite awhile. When the email showed up for this Colt M4 upper at the price Arms Unlimited was asking, I pulled the trigger so to speak. Three days later it was mounted on my lower... I'll buy from Arms Unlimited again.

Great price for quality equipment
This was a great purchase. I had to finish out this build but I didn't want to sink too much money into it. The service and communication was great.

Nice addition to my safe, should've bought two!
Nicely milled, good clean edges. Good finish. I was surprised there are no Colt markings on this upper that you can distinguish as it being Colt from a quick look, but, it comes in a Colt box....with a serial number... This is my first upper purchase, wasn't aware there is a s/n on an upper. Anyway, I really like this upper, it fit my Colt lower nice and clean, no overlaps where they meet, coating is super close to the same as my lower from another AR. All around great purchase. I will most likely order more from these folks. I had a shipping issue where the post office held the package for a week in Shipping city. I contacted arms unlimited and that same day they got the package moving again and it was here in three days. So if the post hadn't dropped the ball I would've had my purchase in three days. Fantastic arms unlimited folks still in my opinion. I can't wait to see my next good sale item from them headed my way.
