There is a new AR-15 buttstock on the market – the TI-7 from Tactical Intent. It appears to combine features from several successful stocks that are already on the market with a dash of its own unique elements.
The TI-7 has integrated storage compartments for battery storage. These tubes are placed in such a way that they enhance the cheek weld of the user. The adjustment lever is shielded from accidental contact. There are plenty of sling attachment points including a QD sling swivel receptacle.
One of the more interesting features to me, may seem mundane to others. The shoulder pad actually curls down under the toe of the stock. I use the toe of the stock to pivot the rifle up from low ready so this shape looks like it would be very functional.
