Well boys I sent my Daniel Defense back for warranty…
I have a 16 inch DD4 RIII that I run suppressed with a Surefire Mini. I was at the range and it jammed with the bolt about 1/4 to 1/8 inch away from being fully seated.
I tried everything to get the bolt back, including mortaring it.
I then took the upper off of the lower and when I looked down the BCG it almost appeared to be canted slightly within the upper, to the right.
Brought it to a gun smith at a pretty popular gun store and the gunsmith told me they’re going to have to send it back and that he hasn’t seen a bolt that stuck in a long time.
Hoping to hear back from DD soon as it was shipped a week ago. Wish I had some photos to post but didn’t think of it at the time when I brought it in. Will post an update when they get back to me.
I was shooting Hornady Superformance Match 75 grain.
Only modifications I had was a Radian Raptor CH and a Geissele SSAE.
UPDATE: Hornady Superformance blew a primer and it ended up lodged by the cam pin.
