Titanium is the best - Jacob Grey Firearms Low Profile Titanium Gas Blocks

I recently got one of these and put in on my .223 AR15 and I love it. Every product I've gotten from Jacob Grey has been great quality just like this gas block. Very smooth finish and clearly very well made. I feel like this is a decent price too as titanium will always run a few more bucks but it's worth it to shed a little extra weight on your rifle.
