A couple of months ago I bought a Surefire M73 rail setup. I was unlucky with the first one.....since my GG&G foregrip would not fit on the rail. I do want to say that George from Surefire made everything right. It did take a while with looking at several GG&G grips, and several M73 rails.....but I feel that Surefire has taken a very open appraoch to making their products the best.
Thanks to George S from Surefire for taking care of a long term Surefire customer. Based upon their actions....and attention...I am planning on installing 2 more Surefire M73 rails on my weapons.
