Is there any reason to stay away from Ti gas blocks? They’re a tiny bit lighter, although it’s unlikely I’ll notice. I’m more concerned with any problems with them, rather than whether it’s the right place to spend my money.
I don’t see a problem using one but don’t know why you would unless you were trying to shave every ounce possible off of the build with NO regard for cost. If building from scratch the best bang for your weight saving buck is a KMR rail and ELW barrel.
Plenty of Full auto through titanium blocks, and no problems at all so far.
Good to go.
