Time to start saving pennies. Threaded for silencers from the factory, eh?
I was contacted this morning by someone asking for rights to a photo I had taken, years ago, of Eric Hertz. Eric was an incredibly decent man with the joie de vivre that carried into all interests h had. A former student pilot, I asked about a model plane on his desk; he said it was his plane, and they gave you a model when you bought one. That plane was located off the coast of New Zealand; Eric and his wife Kathy are presumed dead. Horrible news, best wishes for his family and friends.
The owners of AR15.com are selling a huge stack of firearms to finance the move to Dallas. If I had a spare couple dozen grand, there are some nice rifles I’d pick up. The list is growing as time goes on, so watch carefully.
The barrel nut is at the back of the rail, against the upper. Buy one of these and use as appropriate. The rest is obvious.
Alpine coaster. I never knew this was a thing; there are tons of videos of ones looking more or less sketchy.
