Somewhat of a thread drift but your tripod placement has spurred a thought regarding the AX/ASR chassis.
Does anyone know what the purpose of the lump in from of the mag well is for on the AX series of rifles?
It made sense as a hand hold on the original AX rifle but seems to be an odd 'feature' to still have, unless there is an purpose for it I'm not seeing.
Seems to me like the ATX would be far nicer to shoot of a tripod than the AX/AXSR due to the considerably lower centre of gravity.
