Graco provides a superior product, excellent workmanship and genuine customer service. I have had 2 adjustable combs installed in the past. Both have been expertly installed and withstood thousands of rounds, functioning perfectly. I often receive compliments and questions as to who did the work. My response is always, Graco is the only outfit I trust to install an adjustable comb. I bought myself a Christmas present, the stock is on the way to Graco.
