That's is cool. I've never seen one of those. In fact, I've only fired two A1's in my life.
I had one of the little CARs years ago. I think it might have been an 11'' barrel with a 5'' inch birdcage. Lot's of fun to shoot. Said SP1 on it.
For the guys working on these;
Are most of the springs and kanibly pins the same from A1 and A2?
Would in be against 'mall ninja edicate' to to just use an A2 lower till parts are available?
Will the upper fit on a TM home brewed?
I seem to recall something about a different o.d. front takedown pin.
Thanks in advance.
