Titanium is my favorite - Jacob Grey Firearms OPMOD Titanium Ultralight Gas Block .750

I'll start by saying I love titanium parts for their slick look and for their lighter weight(less than 10 grams). This is a very well made gas block at a reasonable price for Titanium. When you're buying anything titanium you need to keep in mind you're going to pay a little premium as titanium is one of the strongest and most durable metals. The fit and finish were great on this and I installed it on my Jacob Grey AR10 build. Jacob Grey makes a very high quality product so it is nice to see an Opmod product from them. If you're looking to add a little pizaz to your rifle and get rid of a little weight, I recommend this product.
