MIKE-102 Gen 2 5.56 Buffer-less Upper Receiver:
Foxtrot Mike is well known for its innovative 9MM PCC, as it has been a go to for competitive PCC shooters and consumers alike, for more than 6 years. Tow years ago Foxtrot Mike Products has offered the Mike-15 5.56 Gen 2 Upper Receiver. Modern, lightweight, simple and Direct Impingement in a premium quality “buffer-less” upper receiver,. Designed with several innovative and patent-pending features that make it one of the most innovative AR-15 uppers on the market.
Foxtrot Mike launched the Mike-102 after production testing the Mike-102 Production Samples at Kalash Bash Texas back in Sept of 2022. Then Red October in October 2022. The production samples performed well, but they continued to listen to user feedback and made small improvements to the Mike-102 before they launched the Mike-102 in February 2023.
The integrated, proprietary direct impingement integrated recoil system, allows for the upper to function without the need for a lower with a buffer tube, making it a great option for AR style firearms, that incorporate a folding or collapsible stock. Foxtrot Mike Products has listened to consumers feedback about the Mike-15 Gen 2 platform, and have continued to make incremental improvements to the platform due to the excellent feedback they have gotten to date.
The Foxtrot Mike Products Mike-102 Gen 2 Upper Receiver is available in 5.56/223 Wylde and features a forward charging handle that is easy to operate and offers improved ergonomics compared to a traditional charging handle. The charging handle location will make sense to any AK user. Non-reciprocating, and able to be position on either side of the upper receiver, to accommodate left or right-handed shooters.
The reduced reciprocating mass, lighter weight, and higher pic rail on the gen 2 Mike-102 Upper receivers (.250” taller than Mil spec), allow shooters to experience a Modern 5.56 AK variant, with less recoil, and quicker follow up shots due to flat shooting recoil impulse. The operating system is simple direct impingement and has less parts than a standard AR-15, which has helped with reliability of the Gen 2 platform.
The integrated recoil system is simple and utilizes Direct Impingement gas system. The proprietary bolt carrier is light weight and shorter than a standard AR15 bolt carrier. The carrier key (gas key), has an integrated recoil lug, which has a mating pocket in the proprietary bolt carrier. This ensures no recoil load during cycle is distributed to the gas key screws.
The recoil springs have a “nested” inner spring (6 pound), and outer spring (12 pound) , both wound in opposite directions, to ensure they move freely during cycling of the firearm. Inside the nested recoil Springs is the recoil rod. The lightweight proprietary Gen 2 Bolt Carrier Group ride along the Recoil Rod as the gun cycles.
The Lightweight M-Lok compatible handguard, has an interlocking tab with the upper receiver, ensuring proper alignment with the bore. Two Torx bit screws hold the handguard in place for simple maintenance with less risk of stripping screws. An extra long, lightweight barrel nut improves torsional support to longer handguards during hard use, offering a rock solid mounting platform for accessories.
4 position, non-reciprocating charging handle, can be mounted on either side of the handguard, to accommodate left and right-handed shooters. The charging handle is located in the best location for ergonomics, as it is located near your hand on the handguard, and will feel very familiar to AK users. This allows shooters to clear malfunctions, check the chamber or make ready, all while looking downrange at your target.
The “trolley” is the steel carriage the 4 position charging handle attaches too. The Trolley resides inside the hand guard, it is a round tube machined from hardened 4140 steel, with a 4” deep gun-drilled .160” diameter hole down the center of it.
The 4 position Charging Handle has redundant attachment methods. The Charging Handle is held in place by (2) 10-32 set screws, which are installed from the front of the handguard using a 3/32” allen wrench. The trolley also has a threaded end which also compresses against the 4 position charging handle from the rear of the charging handle. The (2) set screws lock the charging handle down from the front of the upper, the trolley locks it down from the rear of the Mike-102 Upper receiver.
