Test & specs: SIG Sauer 716 DMR Sport in .308 Winchester

The SIG Sauer 716 DMR Sport in .308 Winchester in full view

The SIG716 Patrol semi-automatic rifle chambered in .308 Winchester already had to prove itself on these pages a few months ago. Now, we test the other civilian variant of the AR-10 Clone built by Sig Sauer: the SIG716 DMR

Autoloading rifles based on the AR-platform are today part of the standard offering of all major arms manufacturing authorities. Many of them also manufacture semi-automatic variants that are adapted to the civilian market. 


SIG Sauer did so as well: The AR-10 line, which is designed for the more powerful .308 Winchester caliber, bears here the designation SIG716 Sport. It is available in Patrol and DMR sports versions.

SIG Sauer 716 DMR Sport in .308 Winchester: the structure

The SIG Sauer 716 DMR sport in .308 Winchester in full view
The SIG Sauer 716 DMR sport in .308 Winchester is available in two versions.

If one compares the SIG716 DMR Sport with the tested Patrol variant, it is the approximately 3 ½ centimeter longer 18-inch barrel of the DMR attachments that actually make up the difference between the two model variants from SIG Sauer's US plant in Exeter.


In the 3, 6 and 9 o’clock positions, the hand guard has a 324 mm long Picatinny rail. The top rail of the hand guard measures a total length of 520 mm and runs only a short distance from the rear end of the upper receiver. 


As on the Patrol model, on the rail there is the same folding sight with laterally adjustable peep sight and height-adjustable beam front sight.


While standard components are usually used with the Patrol, the DMR variants are more likely to be made up of attachments from renowned aftermarket suppliers. Approximately ten cartridges PMAG10 of the third generation, the trigger guard, the PRS buttstock and the pistol grip with interchangeable backstrap and fronts come from Magpul. 

SIG716 DMR: Semi-Automatic with fine attachments

The sports variant of the SIG716 DMR comes with Magpul’s MIAD grip on which the rear, as well as the front part, are interchangeable.

The PRS stock can be individually adapted to the shooter: by means of a knurled screw each, the stock length and the height of the cheek piece can be adjusted in a resting manner, and a Picatinny rail is concealed underneath a cover on the underside, in order to receive a monopod. 


Last but not least, the sporty DMR variant SIG Sauer also misses a two Stage trigger of the Geissele. This two-phase trigger was dry after about three millimeters smooth take up and triggered resistance after a total of about 2,100 g. 


All this combined, the SIG716 DMR weighs barely 5.7 kilos – without ammunition, optics or other attachments. If you put the supplied bipod with its adapter on the hand guard, approximately 430 g is added to that.


But all this also explains why the SIG716 DMR at the price of €3,999 costs a thousand more than the Patrol version.

The ventilation opening directly in front of the gas block turns out to be larger for the SIG Sauer 716 DMR Sport in .308 Winchester.

Another bare K624i riflescope was joined to the bipod for the precision test on the 100-meter track. Although the mercury column of the thermometer had leveled out a few lines below the neutral mark, the test weapon performed its duty reliably and trouble-free. 


It may have been as a direct result of the freezing temperatures that the testers did not quite reach the 25mm pattern radius presented by the factory gun on the target proof with the 168 grs RWS Target Elite. They managed just a 5-series group of 28 mm with this loading. The testers then came a millimeter closer to the test target using the 168 grs Sako Racehead loading.

SIG Sauer 716 DMR Sport in .308 Winchester: the conclusion

SIG Sauer makes its way in terms of price through to the super-heavyweight class on the European AR-10 market with the SIG716 DMR but still it invoices a good €600 more in return than Heckler & Koch for its MR308 A3 with G28 accessories package. However, the latter, is also somewhat more sparse than the accessory package of the SIG716 DMR.
