AR15

Try jamming yourself right into the corner, use the walls to support yourself and try to get low enough to rest your elbow/arm on the outside. If you jam yourself in you can pretty much just let your right leg dangle and use your left as the thing forcing you into the corner. Leaning out the front of a trench (especially a shallow one) off a bipod is actually pretty damn unstable and forces an unnatural position IMO. Try just shooting with the mag rested as the bipod may be to high. With a bit of practice you can get a really stable and comfortable position that's is often better than prone.
