Kalashnikov USA is proud to introduce the “OMEGA SERIES” of KR-103 side folding 7.62x39mm rifles. We did not hold back when building this rifle. We partnered with Sureshot USA and are proud to offer the very first “6” slot free float MK3 Chassis to come out of Sureshot USA. We then added the Sureshot M4 folding skeleton tube adapter (matching Cerakote) along with the battle proven B5 systems Bravo stock.  We then added the custom KUSA/CMC 3.5 lb. AK Elite trigger for that crisp trigger pull. 

     A Kalashnikov USA/Blue Force Gear AK sling has been added along with a Bravo Company M-LOK QD adapter and a Krebs Customs enhanced safety lever for easier manipulation. A Barwarus Cayman muzzle brake has been added for overall recoil management and reduction. We rounded out this package by including our Extended charging lever, a Bravo Company vertical M-LOK grip and 5 Kalashnikov USA 30 round Magazines. These OMEGA SERIES of guns are hand built and custom fitted by our gunsmith. The Omega Series are some of the finest kitted rifles available.

Based on the Russian AK-103, the KR-103 is our semi-automatic rifle 100% made in the US. This gas-operated rifle comes with a 16.33 inch, chrome-lined, cold hammer-forged barrel. It is chambered in 7.62x39mm and feeds with a 30 round magazine. It has a forged trunnion, a forged carrier, side optic rails, and an improved muzzle brake. 

KR-103 SFS is a dependable, robust, and high-performing rifle made to give you the best experience of an AK. It is a built to last rifle with the reliability of Kalashnikov USA™. 

  • KR-103 SFS is from Kalashnikov’s AK-100 series and exhibits the same reliability that made the original AK-47 one of the most prolific firearms in history.
  • The chrome-lined cold hammer forging makes the barrel withstand excessive heat and wear and tear, giving the barrel a longer life.
  • It comes with a side-folding buttstock that folds to the left of the rifle with a latch. The side-folding makes it easy to carry the rifle.
  • The 7.62x39mm chambering gives you the chance to shoot with the traditional round chosen by the Russian Army.
  • The KR-103 SFS is compatible with a wide range of furniture and accessories of the AKM and AK-74.
