Older bushmasters are pretty close other than the lack of park under the fsb. Same reason people get boners for Colt 1911s, single and double action revolvers. They are Colts. Quite arguably the most iconic firearms c ompany in American history. Lots of copies, some better, some worse, but only one colt. Use to be that if you wanted a Chrome lined barrel, you had to buy an A B C AR. Armalite, Bushmaster, Colt.
10-4, I've heard this quite a bit. Was just curious if there was something different I hadn't heard.
