Just in case any more SDM's or sniper teams minus the new SR-25 come searching for more info on their 14's, I would love to add to the forum. The 14 that is on typical line companies varies, any where from 1-3 MOA (per the schoolhouse, and AMU) depending on the SWS itself. Just as Mr. Gene Econ said, the barrel is going to be beat. To ensure you get the 850 M the M-21 book says you can, you need the match grade barrel. The trigger assembly gets re-done if it does have the match grade barrel too. If that is the case, you sir, have halfway to a 21 SWS. The only real thing left is the match grade sights, which the peep hole will be tiny. If you put a leupold 5X at a minimum that qualifies as the m-21.

Sage Tactical makes a rail kit for $900 that is completely worthless, except that you can put a PEQ-2 on it so you don't have to carry 2 weapon systems for day and night. Yet the Army insisted on spending thousands on it. The cheek weld is beyond awkward and hand position is unnatural. So avoid it if there are possible other options. But if unit SOP's dictate you need it, i guess adapt and overcome.

If you get all of the aforementioned goodies, even still the weapon can have issues grouping. Cold bore might be fine, but give the weapon some use and see what it does.

Everyone wants to look as high speed as they can, and I see too many line company E-5's and E-6's carrying the SWS thinking that they are now qualified to shoot it, when they can't even tell me the formula for elevation, much less the definition of an MOA. If you are not intimately familiar with the weapon, as in your DOPE book looks like a Dr. Seuss book, then I highly advise leave it at home. If you don't even know what DOPE is leave it in the armory. Max effective range of the M-4 is 500 M, and a JDAM is infinite.
