I thought I'd share some pleasantness with my fellow shooters. After one of the worst days in recent work history I came home to a package at the back door. . . ended up being something for the girls from the out-laws (in-laws ). Cool for the kids though! Then I hear the sound of the UPS truck! YIPPEE ! ! ! I was expecting a couple small orders for accessories and such and I always like to open stuff up, but today the box was much longer than anything I had ordered. . . A SURPRISE ! ! ! I looked at the label and it was from Del-Ton ! ! ! I sent them Scrapy after not being able to get enough pressure out of the barrel assembly to cycle the rifle completely. . . Not the manufacturers fault. I ordered the part kind of by mistake. I read in the description "Dissipater", so I thought it would be set-up like my Bushy: 16" barrel/carbine length gas, however this design was a 16" HBAR with a rifle length gas system. I was skeptical right away, but had everything to get it going (it is a pieced gun ya know!)*. Right away the gun was experiencing short strokes and cycling issues, so I called Del-Ton and met Laura. She is such a great person and was helpful from the beginning, even though it has been a few months since the purchase. We corresponded back and forth with trials and test performed by myself. After a few, the rifle was still not cycling completely, so she offered for me to send the entire upper in! They tested it in the shop, by someone who knows a lot more than me about AR-15s and came to the common conclusion that not enough gas was getting through the tube and into the system, so she offered to replace it, with a different set-up. . . FREE OF CHARGE! ! ! She asked what I wanted as a replacement. I told her I didn't care as far as profile, just a rifle length gas system and to surprise me. She sent the beautiful 20" w/ a light weight profile. Del-Ton review: 1.) Awesome barrel! 2.) excellent service 3.) Fast and quality build with the parts provided.
