Start Your SBR/Pistol Build Right with This 300 Blackout Stainless Barrel

The Seekins 300 blackout stainless barrel takes that great little round to the next level of performance. The 300 blackout round was created to perform at its peak with heavy bullets fired subsonic from a suppressed SBR weapon. Bingo, Seekins little 8-inch 300 blackout barrel fills that ticket. Cleverly incorporating a 1/7 twist that flings rounds over 69 grains best, put that 300 blackout stainless barrel at the head of the pack.

Additionally, Seekins machined M4 feed ramps into their 8-inch 300 blackout barrel. This feature gives you a wider range of choices in ammo without the FTF problems apparent without this upgrade. Now, if you want an up-close CQB thumper you need to suppress that little beast. Again, this idea was a component in the creation of the 300 blackout round. The Seekins 300 blackout pistol barrel comes to you with standard 5/8 x 24 threads just waiting for your suppressor. The non-glare bead blast finish won’t reflect harsh light into your eyes and looks great besides.
