Answers to your questions:
Anyone have one of these? Quite a few TFLers do. I shot mine today. Do a search and you'll find several threads praising these guns. Note: some have had a few problems that needed to be fixed. Generally related to burs in the channel for the extractor. Easy to fix, even if you don't tinker with guns much.
Are they accurate? VERY. Today I got 1" groups at 50 yards with the standard iron sights.
How are the triggers? Its not a match trigger, but its not bad. Typical military two-stage. Some slack, then a 3-4 lb pull with just a tough of creep. Not bad enough to hurt accuracy.
Weight? Haven't weighed it, but pretty light. It feels much more ergonomic to me than my Ruger 10/22.
Any good sources for the best ones? Dunno. Bought mine locally.
www.gunsnammo.com had them advertised for a long time, but don't show them now. They may still have them? Visit the website, get a phone number and give them a call.
Thanks. That's what we're here for.
