Too Much Fun

Finally got around to shooting the P716 with a suppressor, makes it a whole new experience. It's obvious why these come with the gas system set up for a suppressor once you start sending rounds down range. I had burned through 60 rounds before I knew what happened, took longer for the suppressor to cool down.

Wow.

That's a lot of unburnt powder to deal with...

I'm imagining all that powder going boom inside the baffles.

Can your AAC take it?

It is rated for a 12.5 inch 308 full auto so it better! I was thrilled that there were no function issues. I was shooting some cheap Magtech M80 ball, same stuff sticks in the chamber on my Matrix build but I know it has a tight chamber.
I'm thinking I need to mount a scope on this rig and see how accurate it will be.

If you do I'd be curious how much your POI changes.

Sounds like great fun - with a very Nice rifle!! Yeah, some bullseye shooting is a good way to go - will slow down your trigger finger too! Thanks for your pics

Cheers

The P716 was a big disappointment today! After another 20 rounds it started to act under-gassed, short stroking, no bolt lock back, etc. Turned up the gas and it ran good for maybe 20 rounds and started acting up again. It especially disliked M118LR, I'm thinking it is a slower burning powder that has a pressure curve not suited for such a short barrel....maybe. M80 ball type ammos only had issues every fourth or so round after turning up the gas. The crux of the problem is the extra gunk a suppressor deposits in the gas system. It may be cleaner in the chamber but the gas piston started forming a coal mine! So much for piston guns being more reliable, the Matrix DI gun has three times plus this many rounds and is still trucking along with the suppressor and no cleaning. The 300 BO is over 400 rounds suppressed, no cleaning, and not missing a beat. The Sig P716 is looking pretty needy!*It did put out some 1 MOA groups with no noticeable POI shift when shot without the suppressor. When I put the LaRue MBT trigger in it I'm betting the groups will improve, now if I could just get the functioning to improve with the suppressor...........

Went out yesterday and did the same ... (Great minds think alike?)

New factory replaced 716 (thank you SIG for replacing that POS gen1)
Bushnell Tactical HDMR 3.5-21x50
Geissle SSA-E
Rugged Surge suppressor w/muzzle brake mount. (Will never be fired w/o suppressor, OUCH!) + Rifles Only HAD suppressor cover.
M118LR. 50 rounds
Federal Gold Match 178 grain

Fired twenty rounds on freshly cleaned and detailed rifle suppressed in suppressor mode. Got a couple failure to feeds in the first ten round mag. After that, it settled down and got reliable operations. Ten round groups ran in the one to two MOA range. Pretty disappointing and getting discouraged.

Cracked open the 178 grain Federal Gold Match and holy guacamole!!!!! We are in SUB-MOA territory .... first time ever I shot that tight with the 716!

Here is what is strange. I went back to the M118LR and those groups were almost if not as tight as the Federal Match. Several three round groups in that ten shot string/group printed cloverleafs.

Shooting suppressed without any type of mirage abatement device on the suppressor is a waste of ammo. Especially with telescopic sights. Even with the RO-HAD on the suppressor, twenty round string under five to ten minutes is the maximum before mirage impacts accuracy.

I know I get a POI adjustment with the 168 grain match ammo of about 1.5 inches. I did not test the 178 match ammo because shooting with a muzzle brake is very unpleasant. I'll try it next time I go to the range.

I'm also not cleaning to find out what the limits are like what jtallen experienced. I have sixty rounds through it.

I'm also using Mobil 1 high mileage synthetic oil for lube. Been very satisfied with the performance.

After a good cleaning I'm up to 125 suppressed rounds without an issue, wide variety of ammo used but mostly M80 ball stuff. Fingers crossed!
