Some Vers-Pods have an adapter that allows the installation of the bipod, while others use a Picatinny rail mounting + an adapter. The Versa-Pod legs come in various heights, but I find the 9-inch height (extends to 12 inches) about right for me. Depending on the mount selected for the Versa-Pot removal is very easy — either push a latch or loosen the locking screws.
The simplest way to attach the Versa-Pod is buy the V-P p/n 150-200 Tactical Sling Stud Versa-Pod Bipod Adapter ($39.95) and a p/n 150-001 Versa-Pod ® Model 1 Bipod Rest ($89.95). The Versa-Pod website is http://stores.versapod.com/StoreFront.bok?tsetlock=versapod.
There are other adapters on the V-P site. One I like is the p/n 150-807 MIL-STD-1913 Conversion Picatinny Rail M1A and M14 ($68.95) + p/n 150-621 HD Picatinny Rail Versa-Pod Bipod Adapter ($68.95) + p/n 150-001 Versa-Pod ® Model 1 Bipod Rest ($89.95). The M1A/M14 rail will fit most rifles plus it has a sling loop. Depending on which setup you choose, your setup will cost about $158.90 or $227.85.
I am not too much a fan of the Harris bipod because it has too many springs and things to snag on stuff. Most of the common Harris bipods do not articulate like the Parker-Hale/Versa-Pod. I believe the Versa-Pod is the best value for your money.
Thank you. That was extremely helpful.
