Seekins 6.5 CM – Semi Auto Powerhouse by CLAY MARTIN

The Seekins Precision SP10 in 6.5 Creedmoor is a true long-range semi-auto performer.

The world has been waiting for a reliable, available, semi-auto AR platform in 6.5 Creedmoor and today we have it. I got my hands on the latest Seekins Precision SP10 in 6.5, and it did not disappoint.
Why we haven’t seen more semi-auto rifles in this caliber, I do not understand. The 6.5 Creedmoor uses the same bolt as a 308, and in most platforms, the same magazine. That a 6.5 Creedmoor bullet will absolutely out fly a 308 is without question. It also does it with less recoil, which really makes me wonder why anyone would choose 308 in this day and age.
The Seekins Precision model we used for testing is the SP10 6.5, though we have a pre-production model. The chief difference between our test model and what you will be able to buy is the stock. Ours came with a Magpul PRS III, which is a fine stock. But Seekins Precision isn’t about fine. They are about perfect. Seeing the shortcomings of available options, this year they are getting into the stock business as well. Rolling out later this month, Seekins will have an in-house built precision stock, worthy of this rifle.
The SP10 is feature rich.  It has a 60-degree ambi safety and custom in-house billet Seekins diamond plate textured magazine and bolt release. The SP10 right side bolt release is also a bolt lock, making this model fully ambidextrous. The charging handle is oversized and right hand only, but you should only need it once on this semi-auto. From the factory, the Timney Competition Trigger is set at 3 pounds.

The left side of the SP10 features a bolt release, mag release and 60-degree ambi safety.

The bolt release on the right side of the SP10 both locks open and releases the bolt and features the Seekins Precision custom texture that you can also see on the magazine release and ambi safety.

The handguard is unique on the SP10, and M-lok compatible. The shape is a little unorthodox, but in practice works great. It has flat sides that angle to a top rail, and the bottom is totally flat. Trapezoid is the shape that comes to mind, though that is not quite correct. The flat bottom is extremely useful for positional shooting, and I really grew to like it during testing. Details like this really start to matter when you are field shooting, not just slinging lead from the bench. The gun screams quality and is really a work of art.

The SP10 has a match grade stainless steel barrel. The SP10 handguard is flat on the bottom and sides which gives it some big advantages shooting off of different rests.

The barrel is 22 inches, optimized to give the Creedmoor enough velocity to do its job. The length and profile were clearly done for accuracy, this is no lightweight princess. The barrel tapers from a heavy profile to the gas block and a mid profile after. The heavy profile under the handguard is fluted to reduce some weight, but it is still plenty thick. This would be my one complaint about the rifle, though many would argue that the solution is called biceps, and you get them at the gym. The gun isn’t actually that heavy. Seekins specifies 10 pounds, though my home scale says 10.6. For caliber, that actually isn’t overweight. But the front heaviness of the rifle makes it feel like 15. Having carried this thing around for a week, I was actually shocked to see the real weight. Seekins has a reputation for accuracy and obviously weren’t’ willing to risk that on a lighter profile barrel.

One thing I can’t complain about is the performance. With Hornady match ammo, the SP 10 delivered ½ inch 100-meter groups. This was followed by an 8 inch 1025 yard group, in the wind. Anything past 200 for me is done in terrain, so I would speculate the SP10 is actually capable of more than that accuracy wise on a flat range. Those are very impressive numbers for a semi-auto rifle, actually outpacing all but the best bolt guns.

The Seekins Precision SP10 6.5 Creedmoor loved the Hornady Match ammo printing a 1/2 inch 100 meter group. The really impressive performance was the eight inch group at 1025 meters.

All in all the SP10 performed admirably. The Seekins muzzle break, combined with the overall weight, crushed any felt recoil. The accuracy was outstanding, as were the fit and finish. If you are looking for a rifle for either hunting, gun games, or tactical use, this one is a champion. At an MSRP of $2650, it isn’t cheap. But if you want out of the box performance, that is the price of doing business.

Between the weight of the rifle and the Seekins ATC muzzle brake the SP10 is very easy to shoot with minimal recoil.
