Worse customer service ever March 23, 2016
Reviewer: omar macias from San jose, CA United States  
I will no longer buy from delton they have lost me as a customer for the following. They shipped me this rifle kit and when I received it I informed them of the defects. The upper came with scratches and a major ding. As for the scratches on the upper they actually forward me a link of touch up paint  and said I have to buy that on my own which I felt offended. They shipped me defected products and at the end they said if I wasn’t happy I can always return everything at my cost for shipping and pay a 15% restocking fee. I have pictures and emails to prove all this I wish I could add all that in this review.

Had Problems with it.... September 27, 2012
Reviewer: MJShea from Lancaster, PA United States  
I Can Not,,, Repeat CAN NOT... Recommend that you combine this with a carbine lower. I experienced nothing but Short Stroking, Jams, and Failure to Lock Back on the last shot. To get the delton dissipator to work properly this is the combination it took: Rifle length buffer tube and stock, standard carbine spring, and standard carbine buffer. The weapon is now performing flawlessly with any kind of ammo I throw into it. No short stroking, no jamming, and no failure to lock back on the last shot... This includes Russian steel case ammo. It was ordeal to get there, and cost me a lot more than I wanted to spend. I would love to give this a better review as I really like the rest of the products that I have bought from del-ton, but this one is a head-ache. Del-ton should make this product with a mid-length or carbine system under the rifle handguard.

Time well spent? YES... April 16, 2012
Reviewer: General Custard from liberty hill, TX United States  
It took almost 8 weeks to recieve my upper. before mounting to my cmmg lower i inspected the internals of the upper and found no problems. Apon breakin 3 of the first 20 rounds did not feed at all. After a quick reoiling of the upper the next 20 rounds fed correctly. I have not had any problems. del-ton should put some sort of break in paper work with there uppers, and a note that says oil before use. Over all i would say this is a great upper a would recomend it to other experinced or first time ar biulders.

16 inch dissipator with gas block February 4, 2012
Reviewer: Al B from Boise, ID United States  
Ordered the 16 dissipator with the YHM single rail gas block on December 17th.  I received the upper on February 3rd.
What a nice package this upper makes with my Armalite lower.  I couldn't be happier with the delivery time or the completed carbine.
Thanks Del-Ton
