A precision stock usually offers three or more: length of pull, cheek or comb height, and butt-pad height and angle. Some add a monopod mount. The point is to get behind the rifle quickly, lock in eye relief, and repeat the same position. In precision shooting, consistency is the work. These are not every stock on the market. I chose four you see often and two you see less. Start with the Magpul PRS Gen 2 and Gen 3. Both have comb height, length of pull, and a monopod interface. They differ after that. The Gen 2 has a flat Picatinny section under a cover. The Gen 3 needs a separate M-Lok rail, and that mounting area is angled, which shortens monopod travel a little. The Gen 3 does let you set butt-pad height and angle, and it can go on a rifle-length or carbine buffer tube. It ships with both adapters. Even with that option I would not put it on a carbine tube. A rifle-length tube is threaded at the rear and makes a more solid joint. I prefer the Gen 2. It is heavier, so it soaks up a bit more recoil. It already has a flat Picatinny section, so you do not buy an extra rail. I will put a Gen 3 on another precision lower later and compare them after real use. Next are the KFS Industries Tacom stock and the CAA multi-position sniper stock. The Tacom has comb height, length of pull, and butt-pad height and cant. It comes with its own tube. I do not have hands-on time with it, but capable shooters I trust do. I do not see an obvious monopod mount; something aftermarket may exist. The CAA has a butt-pad adjustment, a built-in monopod, comb height, and the comb can slide forward. When it does, support under the front of the comb thins out. I do not like that. Length of pull extends the same way: as you run it out, bearing surface shrinks. Again, not a feature I want on a precision stock. Last are the Luth-AR MBA and the Strike Industries Viper modular stock. The Luth is popular for good reason. Think of a skeletonized Magpul PRS. Comb height and length of pull are there. The cheek piece also slides fore and aft like the CAA, but it keeps support as it moves. The platform is modular: buy the fixed stock, then add comb and length-of-pull kits later. Luth also makes a carbine-tube precision stock with comb, length of pull, a rising butt pad, a Picatinny monopod rail, and a lock screw to take out wobble. I still would not choose a carbine tube for a precision build. The Viper is essentially a fixed rifle stock that mounts on a carbine tube, and it locks better than the usual friction-on-carbine designs. The first section slides on against the castle nut and end plate. Spacer sections set length of pull. A nut plate drops into the tube detents and a long screw clamps the stack. For a carbine-tube stock, that joint is solid. Adjustment is coarse, not fine; you pick length when you assemble it. Strike makes a monopod that stows in the stock and a thicker butt pad. Unlike the others here, the Viper has no comb-height adjustment. I am using the same scale I used on the Hera Arms thumbhole review. Magpul PRS Gen 2 and Gen 3: A. Magpul is the practical standard now. Mil-spec is the floor, not the goal. KFS Tacom: A. Full adjustments, solid, and light enough to carry in a match. Luth-AR MBA: B+. It has what you need, it is lighter than the Magpul PRS, and it is affordable. Strike Industries Viper: C+. Cheap, a few of the right adjustments, a good carbine-tube lockup, and they could add a comb later. It is not a full PRS stock. CAA multi-position: C+. The polymer is acceptable and the adjustment list looks complete, but some of those adjustments are not rigid enough for the price. Prices, roughly: CAA about $430; KFS Tacom about $250; Magpul Gen 3 about $230; Gen 2 about $200 or a little under now that the Gen 3 is out; Luth MBA about $130, or about $50 for the base stock if you add kits later. The Viper is the least expensive. The extra butt pad is about $15 and the monopod about $20. If this helped, like and share. Merch is at ballisticink.com under Fitty Actual.
