  1. Great video. Just a note: spacing the gas block for a GI handguard retainer is only necessary for military contour barrels. The spacing is not necessary on most modern sport rifle barrels which are designed for free float handguards. Using a dimpling jig is the best and easiest way to insure best gas block alignment. These dimpling jigs can be purchased online for about $35. This comment is meant as an extra note not a critique. Again, great video. Thanks for posting.
