Optimized Combat Stock For Ultimate Weapon Handling & Performance

The FAB Defense GL-CORE S CP Buttstock is an upgrade for AR-15/M4 and AK/VZ(with Cheek Rest) Platforms to improve weapon handling and performance at shorter ranges. It is known to be specifically designed for one of the best Israeli Counter-Terrorism units, to be used as a primary buttstock.

The design of the GL-Core S CP buttstock is the result of the implemented design changes that have been requested from multiple sources including law enforcement units. It can provide the shooter a reliable stock that is short and compact for CQB scenarios but will still provide strength and stability for mid-range engagements.

Not completely satisfied with purchase.

Item was listed as new and priced at brand new price. However item was definitely used and had an obvious nick on the side of the buttstock where it was dropped or hit against something. Also I’ve bought items direct from FAB defense and their items are in sealed bags with packaging to prevent item from moving in the box. My item from AT3 was not in any bag and all packaging was missing with the exception of the manual. I would normally not take the time to review this if I’d have known the item was used and had mild damage from use and charged accordingly but this feels more like false advertising and that I was definitely over charged for an item known to be used and sold anyway.

So sorry to hear about the issue, Shawn. We sent you an email to resolve the issue.

Very satisfied with this buttstock...

The product arrived in a timely manner...it looked just like the picture online. I installed it to the buffer tube very easily and it fit very snug. I'm very happy with the look and feel stability to my cheek.
