A: Hi Jeff, yes sir, the rifle-length gas system features a 0.750" 4-position rotary-regulator gas block to achieve ideal function across the wide range of ammunition available in the marketplace today. The included, on-board 3/16" ball-end wrench makes for easy regulator adjustment. Stay safe & have a great day!

A: Hi Jeff and welcome. This will depend on when this rifle was manufactured. You would need the Serial Number to have Ruger determine if this has the new gas system. Current rifle gas system details on Ruger's website here : https://ruger.com/products/sfar/specSheets/5611.html

A: Not meaning 7.62×39 but 7.62x51. 308 is actually a bit higher chamber pressure than 7.62x51, so the 7.62 is safe from a . 308 but not necessarily the other way around. While most 7.62 weapons can probably handle most . 308 ammo just fine, you should make some effort to make sure before using your particular combination.

A: Hi Adam and welcome. No Sir. Just .308 and 7.62x51 ammunition. 7.62x39 is a smaller round and won't properly fit the chamber. Details of size difference here : https://www.bearcreekarsenal.com/blog/762x39mm-vs-308-winchester-battle-of-the-cold-war-cartridges.html

A: Hi Adam, no this will not fire 7.62x39mm . It will fire 7.62x51 or .308 Stay safe & have a great day!

A: just 7.62x51 (nato) or .308 ammo 7.62x39 will not work

A: You didn't miss the weight, it's not in the description but I've got it for you. 7.5 lbs

A: Hi Steven and welcome. Unloaded weight is 7.3lbs and fully loaded with 21rds of 165gr .308 ammunition approximately 8.42lbs. Cheers, stay safe and enjoy!

A: Hi Dirk and welcome. The buttstock has a built in QD slot. For the M-LOK Handguard you would need a MLOK QD rail : https://www.budsgunshop.com/product_info.php/products_id/152384/citadel+qd+mlok+weapon+mount ------------------------ And QD Sling : https://www.budsgunshop.com/product_info.php/products_id/152376/allen+citadel+qd+double+point+sling ---------- Cheers, stay safe and enjoy!
