5 of 5 Custom M4 upper 1/7 chrome lined barrel February 1, 2017
Reviewer: RMP from Las Vegas, NV United States  
Great upper @ a great price! Purchased the M4 custom complete upper with chrome lined barrel 1/7 with M-16 chrome bolt carrier group, the fit and finish is great, fit perfectly on my Anderson lower build and functions flawlessly! I've put over 500 rounds through it without any issues!! Shoots tight and accurate groups, I would highly recommend this upper to anyone who wants a quality upper without a heavy price, I will be getting another del-ton upper for my future builds for sure!!

5 of 5 Custom upper January 25, 2014
Reviewer: Robert G from Greenwood, MO United States  
I purchased a custom upper from Del-Ton, built it the way I wanted,  took it to the range and it was a tack driver.  Some of the rounds made the previous hold bigger on my targets.  This is a great upper and I appreciate the way Del-Ton built it for me and shipped it.  A very professiol Company.  My custom build is lighter that my store bought AR-15.

5 of 5 Custom Upper October 19, 2010
Reviewer: Alex from Saint Paul, MN United States  
Just received my custom AR upper assembly, and the fit and finish are fantastic!  The unit fits perfectly and arrived better than expected.

The customer sales reps were very responsive by email and answered my (many) questions professionally and clearly.

Thank you Del-Ton for an awesome AR build... I can't wait to get some rounds down the barrel!

5 of 5 M4 16" Custom 1/7CL Awsome! October 8, 2010
Reviewer: Jeff from Midland, NC United States  
I purchased my upper thru a local DTI dealer based on his recommendation. All I can say is wow! Hornady 75G match will turn out 1/2" 3-shot groups all day long. On the flip side; cheap 55 or 62G Russian ammo will run all day long w/o any issues The chrome lined chamber & barrel allow easy clean up with dirty stuff. If you could only own one upper; this is the one. I'll be buying another soon - maybe a 14.5" 1/9CL or a 7.62x39 conversion.
