PSA Gen2 KS47 Complete Classic Lower Receiver

Lower: The 7075-T6 forged lower receiver is hard coat anodized, and accepts standard AR-15 fire control groups. The extended magazine release is outside of the trigger guard for safety, which allows for an AK-style release movement but also features oversize side paddles for fingertip release by the trigger finger. The KS-47 G2 receiver also accepts standard AR buffer tubes. The KS-47 G2 lower has steel reinforcements to accept AK style surplus magazines including drum-style. This Gen2 design features a PA-10 carbine buffer spring and heavy H1 buffer to ensure reliable operation with a wide variety of aftermarket and surplus magazines.Magazine: The new Gen2 KS-47 has been tested and is guaranteed to work with the following AK-47 magazines:Magpul AK-47 PmagRomanian Stick MagazineRomanian Drum MagazineChinese Drum MagazineChinese Stick MagazineKorean Drum MagazineKorean Stick MagazineYugoslavian Stick MagazineBulgarian Stick MagazineCircle10 Stick MagazineHungarian Stick MagazineRussian Stick Magazine** Due to the unique geometry required for the KS-47 G2 BCG to function, ALL other magazines will not be guaranteed to work. If you are using a magazine not listed above, no warranty claims will be accepted for magazine functioning issues.KS-47 Gen1 & Gen2 Compatibility:The KS-47 G2 uppers and lowers will function with the KS-47 G1 uppers and lowers. However, if any KS-47 G1 parts are used, all of the improvements of the KS-47 G2 may not be optimized. We recommend using Magpul AK-47 Magazines on any KS-47 that is a combination of Gen 1 and Gen 2 parts.Through extensive testing, we have determined that we can only guarantee the reliability of the KS-47 G2 platform with the PA-10 carbine buffer spring and heavy H1 buffer. The KS-47 G2 Lower will accept most aftermarket fire control groups (Geissele, etc.). However, due to the magazine catch geometry, one piece drop in triggers such as CMC style triggers will not function in KS-47 G2.
