I started off with DI SBRs. The first was a 10.5" LMT Mk18 and followed that with a BCM 11.5".
I replaced those with piston uppers (all LWRCs), sold the DI uppers, and have not looked back.
The only reason I stopped using the DI uppers is because I am too lazy to clean y guns with any regularity. So after I started shooting the Mk18 with a suppressor, I had a failure to fire. Turns out I had so much carbon build up on the firing pin that it was not making enough of a dent of the primer.
I have not had any such issue since I bought my first piston upper (10.5" LWRCI M6A1) more than 14,000-rounds ago. I now have 3 SBRs (10.5", 12.7" and 8.5" PSD). YMMV.
