My tuner testing with the B14R has been suboptimal using a bipod . I came across the EGW bag rider for an AR that attaches to a Pic rail. I have a Pic rail on my Bergy for an Atlas bipod so I was set. The bag rider has an ingenious attachment method, is made of Delrin, 3” wide and is railroad tracked. Kinda pricy but seems a better device than my Sinclair “squeeze on the forend“ bag rider.
This product fits:ARs with picatinny on the bottom of the handguard Picatinny rail is not included.The screw that is provided to retract the picatinny crosslug is 6-32 x 1-1/4".
I’ll find out tomorrow how it works.
