Swapped out A2 front sight for receiver height railed gas block

As with all my videos, this is not necessarily a “how to”, but more so to show that YOU too can do basic work on your firearms. Swapped out the A2 front sight for a receiver height gas block and Troy Battle sights front and rear. Sure the pins were in there tight, but with a little force and driving them in the RIGHT DIRECTION, they popped right out.

  1. To anyone who may not be aware and hasn't purchased yet.. The M&P 15 OR (optics ready) comes with a same-plane picatinny gas block. The block itself is pinned and has both a threaded hole to mount a sling stud for mounting a sling or bipod & a QD sling mount machined into the bottom of the block.
    When I was shopping for my first AR (post Sandy Hook) Crazy laws were being passed & the shelves in my area were picked clean. I didn't really notice or care about these features, but I was happy to have them as I upgraded later on. Just a heads up if you're in the market or new to the AR platform.

  2. I have the same M&P and essentially wanted to make the same exact mods. You answered a lot of my questions and I really like the way your rifle turned out. Your video did not come in the first several searches but I'm glad I finally came across it. Thanks again for the info and for making the video!
