We have invested in quality material to design our DSG MK12 SPR 18” barrel, weighing 41 oz. Giving it a 416R stainless steel finish and then coating the barrel with nickel boron, we have succeeded in providing you with a durable and long-lasting product.

When it came to appearance, we went with a bead blasted external finish.Before we could make this product available to you, we performed both HP and MPI testing to ensure our barrel passed with great results.

Our barrel is made for special purpose rifles (SPR), which are semi-automatic rifles or MK12. When you fire your weapon, its 1:8 twist rate will stabilize the bullets when they leave your rifle. Safety first! Therefore, we have added a .223 Wylde chamber. Further ensuring the proper functioning of the weapon is the 11 degree recessed target crown.

We have also added additional features such as a rifle-length gas system, button rifled, 1/2x28 muzzle threads, and .750 gas block, which prevents bending, increases stability of the weapon when fired, and reduces overheating. If you own an automatic rifle and want to equip it with a sturdy barrel, you can add this DSG MK12 SPR 18" to your rifle.
