I have not held one... one of the youtubers im subscribed too was talking about it in a recent vid and thats how I found out about it... It looks like it would be a great stockAs much as I like the MOE/CTR for being so lightweight, I prefer the better cheekweld on stocks like the ACS, EMOD and SOPMOD. This new stock looks like a perfect blend of the two. Have you held one? I'm wondering if you can pop off the battery tubes to drill in some pins or if they're already pinned in place like the current ACS stocks.
