IS THIS SIGHT MACHINED FOR PINS TO ATTACH TO BARREL ?. IS THIS SIGHT PARKERIZED GRAY IN COLOR ? NOTE THIS SITE IS FOR OLD STYLE FIXED CARRY HANDLE COLT AR 15
CHUCK on Apr 28, 2018
BEST ANSWER: This is an "F" marked sight block which is made to match up with A3 type flat top receivers so for a fixed carry handle you would want a non "F" maked sight block. When it comes to pinning to a barrel, you need to drill and reem when it's on the barrel so once pinned the fit is tight so most sight block come not predrilled.
What size pins will I need to install this on to a new barrel?

AR-15 A2 type front sight
I bought this front sight as part of my building an old A2 type AR-15 (M16) similar to the ones used in Viet Nam. The sight works great & since none of the mounting or securing points were drilled & tapped I had my choice as to how to secure the sight. Since the barrel was dimpled already I just drilled & tapped the rear hole to 8X32 & did the same to the front mounting point (bayonet lug), dimpled the front hole mount &after tapping the front mounting point I cleaned it all off, used blue Loctite on the threads & finished securing it. It worked great when I took it to the range.

Great Quality FSB for Your Builds
I am not a fan of bolt on gas blocks, and sometimes I just want to put together are regular looking carbine. These are the best I found, complete with bayonet lug, unlike some others. Just remember the sight and pins are not included, so grab up some of these.
