Trinity force cobra vs alpha stock - Trinity Force Cobra Stock Kit Combo

The Cobra version has a wonderful cheek "pad" that is great for target ARs. Much like the Leapers UTG PRO Model 4 Combat Ops S1 but in a smaller overall package. The fit to the buffer tube supplied is much better than most, including the Alpha, but still with a little "rattle" when fully extended. The Alpha is really a smaller version with the same quality.

One tip to install the stock (Alpha as well) is to wrap some 1/8" braided nylon cord over the transverse pins, making a two looped saddle, to pull the lever down enought without chewing up your fingers or finger nails. The adjustment spring is darn right stiff!
