No, and I'm really not too worried about it breaking... but...
I bought it a few years back, (60 SB) and It's the best shooting .22 auto I've ever fired. I guess I just got lucky w/ this one. It's favorite ammo is bulk remmy golden bullets, believe it or not... It'll keep 'em inside of 1 1/2" at 100yds... (really ticks off the guys w/ their tricked out 10/22's at the range.) It's a truly fantastic gun, best $165 I've ever spent, and that cheap looking plastic trigger guard just doesn't do it any justice at all.
