Sureshot Armament Group MK2.1 Drop-In AK Chassis -The Firearm Weblog

[ad_1]

Back in February of 2018, we published an report telling about a Sureshot Armament Group AK chassis/handguard technique referred to as MK2. The installation of MK2 expected removal of the rear sight block and gas block and reinstallation of the latter. Even though it is not a complicated process if you have the right tools and capabilities, for most of us it likely indicates taking the gun to a gunsmith. Acknowledging the will need for a drop-in remedy, the organization came up with the MK2.1 chassis which makes it possible for the finish-customers to set up it on their rifles employing just a screwdriver.

The Sureshot Armament Group AK Chassis MK2.1 is compatible with AKM/AK-74 pattern rifles (stamped receiver). It is readily available in two versions that differ from every single other only by the rail remedy (M-LOK or Picatinny rail) on the prime handguard, in front of the rifle’s rear sight. The chassis is compatible with Bushmaster ACR handguards. You can use polymer Bushmaster handguards with the SAG upper handguard, on the other hand, the organization notes that “polymer handguards could need to file down rear finish face to match“.

The MK2.1 chassis consists of the base element, rear sight block insert, upper handguard, gas tube, and reduced handguard. The base element is inserted into the handguard cavity of the receiver and clamped to the barrel by way of the RSB insert therefore forming a base for installing the upper handguard. The latter homes the gas tube and in conjunction with the base element makes it possible for attaching the reduced handguard. Right here is a video (in Russian) displaying the installation procedure.

When installed, the upper and reduced handguards of SAG MK2.1 chassis do not touch the barrel which indicates the pressures and forces applied to the handguard will not transfer to the barrel therefore enabling it vibrate far more regularly shot right after shot. Now I know that technically we cannot likely use the term “free of charge-floated barrel” when speaking about any gas piston operated firearm. On the other hand, eliminating the barrel and handguard speak to does increase the rifle’s overall performance in the accuracy division even although the barrel nevertheless comes in speak to with a major ol’ moving element, the piston/BCG. By not obtaining a direct speak to with the barrel, the aluminum reduced handguard also heats up significantly slower. According to Sureshot Armament Group, “the handguard remains cool even by way of 120 shots string“.

When installing this chassis, you can preserve the original AK handguard retainer but then you will will need a unique reduced handguard with a cutout to accommodate the AK handguard sling loop or reduce a slot in the handguard your self. On the other hand, if you reduce the sling loop, then the Bushmaster ACR reduced handguards will match just fine.

The rail section that protrudes rearward, behind the rifle’s rear sight does not block the iron sights which indicates you can nevertheless use the normal sights if there is no scope attached. A further exciting function of this rail section is that it has a constructed-in slot to straight attach Trijicon ACOG scopes with no employing the Picatinny rail. By straight mounting an ACOG to the rail, you will make it sit significantly reduced compared to attaching it by way of the Picatinny rail. This rear rail portion also will not interfere with the normal disassembly procedure.
