Questions & Answers
Q: How is the fit between the upper and lower? Is there any wobble/play

A: They carry DB's at my local store. I've checked them out a bit and I thought they were put together well with tight but not overly tight tolerances.

A: Hi Casey and welcome. There is very little play in the upper/lower when new. I used an accu wedge on my DB's and other AR's with play to remove all upper/lower play : https://a1armory.com/ar-15-parts/ar15-accu-wedge-red-or-black/ --- Cheers, stay safe and enjoy!
