Well, if that rifle came into the shop and the owner asked what would I
do to increase it's ability to put rounds on target.....
I would suggest a free floated fore end, that will increase accuracy right out of the gate.
I would suggest the 15 minute trigger job, or I would suggest changing out the trigger if target/varmint shooting was in order.
I would suggest dumping that ramp sight and removing that carry handle, getting a good heads up scope for CQB or a scope for target shooting, then getting a set of back up iron sights, just in case.
A good sling if this is your SHTF weapon. I really like a good two point sling myself.
Some good magazines and a few other special tricks, you would be good to go.
You know, if you still had the weapon. Damn shame brother....
