It's a 16" middy with hammer forged barrel. Here's a picture when it had the sightmark but that was returned so I just used the troy battle sights and zeroed at 50yards.
Edit- ugh! I don't know why photobucket still rotates the image after I edit it, sorry, seems to be an issue with iphone pics.
From the very first shot I was like
and more of
It cycled smooth and just felt great!!! Recoil is minimal and the muzzle is back on target very quickly. I think the Daniel Defense Superior Suppression Device may have helped with this as they note reduced muzzle rise on their website. For reference my AR15 experience previous to this was limited to carbine length with standard A2 flash hiders.
Put about 250 rounds of Federal Lake City 5.56 62gr XM855 and 50 rounds of Remington 55gr .223 without a hickup.
I noticed the ejected casings are hitting the deflector- what's causing this and should I adjust the buffer to get them ejecting closer to 3:00?
Here are two pictures, first after the 300 rounds, then after cleaning (the deflector only, didn't clean the BCG yet in that shot). You can see that after cleaning there's a small spot where the coating is worn through already with only 300 rounds. Based on location of that spot it makes me think the ejection is very far back like 5:00-6:00.
Overall- love this rifle!!! Thanks again to everyone here for sharing your experience and providing guidance to us noobs. I'm very happy with the choices I made for my first AR.
