My general opinion is that there isn't an after market BM out there worth
the extra money. For now save your 150-200 bucks and put it towards needed
upgrades like the low pressure 'rock knob', ASA adapter to put a real reg on
there, maybe the Bob Long turbo board and anti-chop eye.
At any rate you can take the money you save buying a stock BM and put it
towards upgrades that'll give you a better gun in the end for the same money
as a defiant.
