Spetnaz Soldier 47 Posted January 18, 2013 Report Share Posted January 18, 2013 Hey guys so I heard that on our Saiga 7.62x39 Ak's, the barrel is bored out of a 5.45x39 (ak-74) barrel to a .30 cal (7.62x39). So does that mean that our barrels are thinner than other ak-47 barrels? Ive been looking at it and it looks pretty thin for the caliber of bullet its shooting.

BigChongus 765 Posted January 18, 2013 Report Share Posted January 18, 2013 My 5.45 and 7.62 are both the same diameter. Quote Link to post Share on other sites
dubya 198 Posted January 18, 2013 Report Share Posted January 18, 2013 I did hear that on another forum. I don't know if it's true but that's what I heard. Quote Link to post Share on other sites
Spetnaz Soldier 47 Posted January 18, 2013 Author Report Share Posted January 18, 2013 Thats what im talking about? Shouldnt the 7.62x39 be larger than it is or is it ok. I wonder if its thickness has anything to do with lifespan or accuracy? Quote Link to post Share on other sites
BigChongus 765 Posted January 18, 2013 Report Share Posted January 18, 2013 (edited) Not in the slightest. They were using this barrel diameter a while before the AK-74 was made. In other words, it was within the design parameters for the 7.62.

Spetnaz Soldier 47 Posted January 18, 2013 Author Report Share Posted January 18, 2013 Oh ok. It just doesnt seem very thick for the ammount of power its carrying and thats funny because supposedly you can get more rounds out of a chrome lined ak barrel than an ar-15 which has a light caliber bullet and a much thicker barrel.
