I'm selling a Harris Bipod...it is model number 1A2-L...a 9-13" model that attaches to your sling swivel stud. This one does not pivot and does not have leg notches. Here is a link to it on Midway:

I've used it once...it is in like new condition.

It sells new for $76.99, I'll sell it to you for $65 shipping included via USPS to the lower 48.

I prefer paypal for payment.
