Just a heads up for you that want an original Modstock at a great price. $49.99.

Both black and tan, standard and clubfoot are in stock.

Thnaks for the heads up. Really tempted to buy but having a hard time figuring out the differences between the regular and clubfoot. Any preference guys?

This is taken from the VLTOR website:
"Even though the Standard model is the most well-known model amongst the shooting public, the Clubfoot version is a hybrid model that bridges the gap between tactical and prone shooting positions. In other words, the Clubfoot portion of the stock allows the shooter, with his/her off hand, to support the stock and to control the rear of the weapon, while shooting in prone or rested position."

If you tend to shoot from a prone position then the clubfoot is designed to offer you a place to put your hand while doing so.
If not then either ome would be fine.

On a side note one of the forum members was selling (and might still be) a "EMOD" stock.

This to me is the best stock made by VLTOR.

The differences are the metal plate on the butt, the rubber butt plate pad and the additional comportment for storage.

The Emod also has a curved butt plate which, I believe, the older models don't have. IMHO the Emod and Imod are better in every way but many won't want to spend $100+ on a buttstock and the older models can suffice.
