Hi, I want to put a graco gracoil recoil reduction system on my gun. I was planning on the GC15 LP but then remebered that I have the LOP on my BT99 and have never once adjusted the length of pull. So what are the pros and cons for getting the LOP (length of pull) or just the standard non lop. It looks like less stock might have to be cut off with the standard. Also where is a good place to get a recoil pad at a good price and what are your favorites? My BT99 has a browning pad but I have also had a kick eeze pad on an old BT99. Whats the best or other options of pads and wheres the best price on them. Looking for options and opinions, Thanks in advance.
