Tonight I acquired an AR in .260 Remington, built on what appears to be a matched SI Defense upper and lower set. They fit together nice and snug. I knew the man who put this gun together and unfortunately he's no longer around. I had thought he built the gun on Aero Precision receivers, but I obviously misremembered.

So what about SI Defense? I can't recall the last time I ever read or heard the name.


Don't be the darkness.

America will perish while those who should be standing guard are satisfying their lusts.
