so you shoot a lot with a bipod and in the prone unsupported position? because i do and i have found out that using the GRIP POD is pretty much cheating in the real world. it's like having that "lame" bipod you are afraid to install because "bipods are gay" a secret. press the little button and voila! you have supported weapon with a much more stable firing platform. also, shooting from the prone unsupported with a bilateral grip is probably one of the most unstable AND uncomfortable positions you could put yourself in. your weak arm stresses from extension and your strong arm stresses from flexion.
oh, you knew this already because you shoot from the supported and unsupported and bilateral grip positions often.....
for the record, on real steel, this is good for one shot at range. then you have to check your support and re-zero. still a cool little gadget though.
