6310KM is based on FCD's 6310 flash suppressor/comp, it is compatible with Dead Air 30 cal sound suppressors. Precision machined from solid 4140 steel bar stock, heat treated and QPQ treated, it is probably the finest A2 style comp/flash suppressor ever produced. Its 3 and 9 o'clock ports are 25% smaller (shorter and narrower) than the other three upward facing ports so more gas is vented through the upward facing ports, it is a superior compensator to the A2, its flash suppression is equal to that of an A2. 6315KM is compatible with Dead Air 5.56mm sound suppressors.
Note that since 6315KM does have flash suppression capability equal to that of an A2, it is to be treated as a flash suppressor for states that feel threatened by them, such as CA, MA and NY. Threaded for 5/8x24. 6310KM is a light and short blended performance muzzle device. It features shorter and smaller 3 and 9 o'clock ports to direct gas upward, this provides 15 to 20% better muzzle rise compensation than the A2, and what is impressive is that it does so without sacrificing its flash suppression capabilities or creating more noise and concussion. The number 63 in its name pays homage to the Stoner 63 light machine gun, the shape of its ports draws heavily from the Stoner 63 LMG's flash suppressor design, KM denotes the Dead Air Keymo sound suppressor interface.
A crush washer is included. Proudly designed and made in USA.

1210KM (5/8 x 24) is Forward Controls Design’s latest offering in the Dead Air sound suppressor mounts line. Threaded for 5/8 x 24, 1210KM is a Keymo compatible brake, compatible with all Dead Air 30 caliber sound suppressors.
Forward Controls Design (FCD) don't like brakes for ARs, they're loud and obnoxious. While a brake will reduce felt recoil, it has unjustifiable compromises in increased concussion, noise and flash signature, one also wouldn't want to use a brake from inside a vehicle or indoors, these are trade offs a flash suppressor doesn't have. That said, a brake for a sound suppressor does have its use as a sacrificial first baffle to increase the longevity of a sound suppressor. For this reason, there won't be a 1215 or 1210 (sans the Dead Air Keymo mount interface), 1215 design will solely reside on 1215KM (1/2x28) and 1210KM (5/8x24).
1210KM is a single chamber brake, with a baffle like chamber forward of the ports--This does nothing to reduce the decibel. The tines on top and bottom that connect the Keymo mount to the front chamber are of symmetrical, FCD think a smaller/thinner top tine to force more gas upward is unnecessary.
Do away with ambiguities and insinuations as to what it is and what it does, 1210KM is a brake, it'll be loud, and its concussion will kick up dust visible from the next county if you shoot it from a prone position without a sound suppressor. 1210KM is meant to be used with a Dead Air sound suppressor attached.
1210KM is designed to have less concussion than most brakes. In terms of felt recoil reduction, most brakes are similar in performance. In the old days, some tank guns brakes are nothing more elaborate than a tube mounted perpendicular to the bore forming a T shape, it doesn't take much to make a brake that works. If one is to look at old tank gun brakes, he will soon realize these tank gun brakes and most muzzle brakes for small arms today bear surprising resemblances and design. To make a brake less offensive is far more difficult. In FCD’s experience, Knight's Armament's MAM brake is probably the best in that category, it's also very costly. 1210KM follows FCD’s design philosophy, it's a simple and effective brake. It does what it's designed to do, and does so without making unsubstantiated claims.
FCD tested the 1210KM against a host of brakes and flash suppressors. Flash suppressors are the least concussive. The one FCD know to be the most offensive was as loud, concussive and obnoxious as ever. Nothing everyone doesn't already know.
The real surprise is 1210KM's performance. To wit, even though the Mk12 brake is the 1210KM's inspiration, it is still an FCD design, FCD did not use most of the Mk12 brake's features. The attributes that helped 1210KM even LESS concussive: a slight larger than 30 cal exit hole (FCD opted to follow Dead Air's specifications). The ports are not angled like the Mk12 brake. The larger bore size makes for a less effective brake, but it's .223 FCD is talking about that doesn't even need a brake to begin with, but it does have significant impact on noise and concussion. The flat sides of the port don't direct gas back to the user, or bystanders behind the shooter. 1210KM's design goals were not only met, but exceeded.

CAUTION!
1210KM has wrench flats for torquing it on the barrel. Do not use a screwdriver and insert it into one of its ports to torque it. With 30ft lbs of torque, using a rod or screw driver will cause damage to the muzzle device.
JMW (Joint Muzzle device Wrench) was designed specifically for use on suppressor mounts: www.forwardcontrolsdesign.com/jmw-joint-muzzle-device-wrench.html
Screw driver not included (but seriously, use a 3/4 wrench, armorer's wrench, or JMW, not a screw driver.)
