The EMOD is based on the same rugged and practical design as the original Vltor Modstock - with specific features designed from lessons taken from the modern battlefield.

The EMOD is about one inch longer than the original Modstock and with the rubber butt plate installed, is about a quarter of an inch longer than the CRANE SCB. The increased length of the EMOD is a major benefit when used on scoped rifles (SPR/DMR), as it increases the available comb for any given length of pull.

The buttplate of the EMOD is slightly wider and longer at the toe than the regular M4 stock with a noticeable negative pitch, making transitions from the ready feel much more natural. The EMOD was given enough weight to help balance out the normally muzzle heavy feel associated with negative pitch buttstocks.
