Customer Ratings & Reviews
ar-15 gas block front sight
Easy to order and fast delivery. Be careful not to twist this as you try to mount it. You'll naturally want to. It must have had a small spur where the hole was drilled into the bottom that scratched my barrel. Apply plenty of lubricants to help it along. I've put about 30 rounds through with no MF. I love that my front site is no longer in my fiel d of view!
PRI gas block front sight
If you are looking to replace your fixed front sight on an AR-15, the PRI would be hard to beat. It is well made, fits just right, and is easy to install. The flip-up control button is also easy to use and well placed. I will definitely get more gear from PRI.

PRO flip up front sight is flawlessly
The PRI flip up front sight is one of the most rigid and properly made front sights I've seen. I'm in the middle of building a M4A1, and this sight sits flawlessly functions as good as any high-end sight should. After researching ar gas block plus front sight prices, this folding front sight gas block was a no brainer.
PRI front sight/gas block
I like the PRI front sight/gas block. Looks great, works great for my build, and an iconic look. They are expensive.
