Friends: Not a weapon expert by a long shot. I just love them is all. I just purchased a used Bushmaster XM-15 E2s . 223-5. 56 cal, 15 inch barrel, telescoping stock. It is scratched up a little. No rail system. Has fixed grab handle on top and standard A1 type features and sights. No flash suppressor or bayonet lug. (ban era?) Has a strange finish to barrel, kind of rough and little sparkles in the finish. I got 3-30 round magazines and a 3x9 power scope but have no idea how to mount that or if it would be worthwhile as I dont plan to hunt with it. . just use it for yard varmints and HD.
Questions: I paid $500 for this weapon because I wanted to own one. I have not fired it yet but I am wondering if the price is in the right range?
I realize it's a little late now, just wondering. Tried to find comparisons on the internet but too many variables to weed out.
What type of finish is this?
Thanks in advance.
