I need to attach my one point sling adapter to my AR. Dose anyone have the wrench to take off the buffer tube or know a way to do it with out it that wont destroy the lower?
You can get the wrench for pretty cheap from Primary Arms. Personally I bought an armorer's tool that has more functions.
Be careful when you loosen the buffer tube. There is a spring held in for the take down pin in the "back" and the buffer stop pin in the "front". I'd suggest putting your lower in a one-gallon plastic bag just in case they go flying out.
