Re: USMC M 40 A1 W/ Unertl 10x scope. Opinions
The sling is not backwards, just attached incorrectly, the single tail end is the back, it is just connected to the front instead of on itself.
Most get this rifle for a collectors item and not so much to shoot.
There is a list, far and wide of better suited modern tactical rifle available. That design, including the scope is over 30 years old and way past its prime. there is a reason its been replaced, twice now. For a collector, willing to spent close to $10k, a well built spec rifle is a fine addition, providing it sits on a shelf. For a shooter, I would look else where, as many companies make modern day clones for much less money with much better scopes.
