I have looked at those bipods, which size did you get and how do you like them, do you flip them up or take them off when you put your rifle away? How sturdy are they when they are fully extended? Lots of questons.
The bipods are UTG TACTICAL/Sniper Profile Adjustable Height Universal Bipod with Rubberized Stand from amazon.
I ordered two one on my 15 only swivels approx 45 degrees but can have a washer placed under the bolt to obtain 360 degrees like my other one.It is 10 inches min from bottom of rail to deck adjustable to12 inches total height with a forward or backward movement of 1 in.
I shot the 15 with the legs locked out fully and locked into my shoulder and was very pleased with the stability and I keep the legs locked in the up position for storage on my 15 the legs point to the front on my 15-22 to the back.
I hope this info helps you if I forgot anything please let me know and I will try to answer it.
