The barrel I have is not Notched as to be able to have extended feed ramps as seen in the above pic, so I am thinking since this is not a rapid fire tactical gun, a varmint gun, I wont need the feed help. Quite the contrary, this will, with a 75-80 gr bullet loaded so my free travel is .05" I wont be running a 30 round mag through it anyway.
Thanks all for the help.
