How do you like the UTG rail?

MAHA

I am actually very happy with it and somewhat surprised at that.  Of course the BCMR 9" was out of stock and possibly a bit much for a rim-fire at over $100 more. It has some great features when you look into it, especially for the price.  The design is also tops and it has a nice finish.  I could not use the shims with the barrel I chose however and did torque the barrel nut more than I wanted to get the screws and inner collar lined up.  In fact I stripped one of them, but good CS though and they sent another collar to me after providing receipt.
