Only option, yet still the best option - JP Enterprises .750 Adjustable Gas System And A2-Type Clamp-On Sight

Sure, there isn't another option for an adjustable gas, clamp-on FSB without a little DIY action. I like a DIY project as much as the next guy, but sometimes I have too much going on to take on another project, no matter the size. This was one of those cases. Plus, the smooth contours of this FSB give it an updated, slightly cleaner look than a traditional FSB tends to have; something I was not able to readily able to recreate. At first, the price point seemed really, really steep. Once I had the product in-hand and then installed, It is worth every penny. Unbeknownst to me at the time of ordering, this FSB, despite being clamp-on, also includes a single taper pin to be used in conjunction with the socket head allen screws for the option of permanently attaching the FSB (for all those that say its not genuine unless its pinned) along with a section in the instruction booklet dedicated to this process. Obviously, you would need a drill press. But hey, pinning the FSB is optional. I highly doubt you could move the FSB with only the clamp-on installation if properly installed according to instructions. This is a super solid option for an adjustable and fully functional FSB. No need to ever have a dissipator set-up again. This is truly the gas block that checks all the boxes. Highly recommend!
