The extra long ERGO F93 PRO Stock 8 position collapsible AR-15 Stock from Falcon Industries
Previously known as M93 (when produced by Magpul), the rights to manufacture this highly adaptable and tremendously admired stock was purchased by ERGO. The F93 has been enhanced by making use of a standard carbine receiver end plate and castle nut that enables high level of flexibility with single point sling plates and adaptors.
USP – Extended Length
The buffer tube is fully enclosed and that ensures fixed cheek support. With 8 positions of collapsibility for AR type rifles, the stock offers extra long pull. In fact it offers one of the longest length of pull in the market along with a fixed cheek piece for a constant and a repeatable cheek weld in any of the 8 positions. The molded carbine length buffer tube system is particular to the F93 stock.
Ease of Use and Reduced Recoil
Recoil is considerably reduced as the stock locks itself on to the sides of the buffer tube giving the user a fixed stock experience. The buffer tube also comes with a bottom rail which can be used with included preset inserts. It enables quick changeover to your custom presets. The stock comes with a recoil pad that ensures ease of use and provides ample security and positive placement.
The sling plate
The sling plate is ambidextrous and comprises of 2 sling attachment points that enable rapid detachment. It also contains 3 web sling attachment points and 2 sling hooks. The wave like pattern ensures that the stock ratchets to the rear.
The stock is about 8 inches in length from the receiver to the butt plate in the collapsed position and about 12 inches in the extended position. It is considerably light as it weighs only about 1.3 pounds. The F93 Strike Plate is also available. Manufactured by the Falcon Industries (Ergo Grip) in the United States, the stock comes only in Black colour.

I am tall and have long arms so the extra length this adjustable stock provides is great. It locks up very tight with no wobble or noise. A very nice upgrade over the standard adjustable stocks.

I own the M93 and love it. You can no longer buy the M93 new, so your next best bet is the F93. I have compared them side-side and believe they are using the same molds/dies that have been modified slightly to remove previous logos.

LOCK UP IS ASTONISHING, I HAVE NEVER FOUND A STOCK THAT TIGHT. THAT SAID THIS STOCK WILL NOT BE USED FOR CLEARING OBSTACLES, DOORS ETC. IT IS STRONG, JUST NOT THAT STRONG. MANY ATTACHMENT POSSIBILITIES.
