Scars are unusually tough on optics due to the 'different' recoil impulse.

I wouldn't assume it was due to the SCARs recoil over it being just a middle grade vortex. Other people have messed up their vortex scopes on a variety of rifles.
I definitely would not blame your mount. I have an ACOG on mine since the second time out and so far so good |

I would really like to see a razor competitor to the 2-10x optics. Perhaps a 2-12x design with first and second focal plane reticles. SFP illuminated large ring with FFP interior cross hairs. Design it so the large illuminated ring is no longer visible at max magnification and keep the center FFP crosshair fine for precision work at max magnification.

Sphur, Nightforce and Geissele all make nice mounts if you don't have to have QD. I no longer use Bobro. Why no Bobro? I had two different mounts in a row loose their ability to hold zero. The spring loaded clamps keep it on the rail, but they don't prevent front to back movement. Bobro uses a spring loaded recoil lug that keeps the mount pushed to the front. Both of my mounts started out holding zero, then later I started having accuracy issues. The spring loaded recoil lugs no longer measured over .210 and were down to about .206. I could grab the mounts and push them back and forth on my uppers. Bobro replaced both mounts. I just don't trust that the lugs won't shrink again after 500 rounds or so. My single lever 30mm Bobro mount was on a rifle that shot about 1 to 1.5 moa. After the mount went bad it was shooting about 4 to 5 MOA. My dual lever 34mm Bobro mount was on a rifle that was shooting about .7 MOA. Accuracy went to about 1.5 MOA. I replaced the mount with a Geissele and shot a .585 MOA entry to the MOA challenge on my first try. I still have the replacement 34mm mount. I should probably sell it as I'm not going to use it. |

I have been using the 1-4 PST in a LT104 mount or Viper 6.5-20 in a LT104 mount no issues. I have several thousand rounds and the optics are used on other rifles as well so they have a lot of miles. Wonder if it was Vortex defect or SCAR that was the issue.
Anyone ever done a high speed of an optic on a SCAR? |

The ADM Delta was designed around the scar platform ..... Super robust mount with lots of surface area contact ..... There is no need for a cantilever mount on the scar as you already know
The delta is what most will recommend on the fn forums ..... LaRue LT111 would also be a good choice |

My SCAR's ate a few optics over the years.....Burris XTR Tactical, Zeiss Z-Point and a Kahles. Finally said screw it and put on a Night Force NXS 2.5-10x42 and it's been great through several hundred rounds. One other newer scope that you may consider is the new Trijicon Accupoint 2.5-12x42. Had this been out when I was buying the Night Force I would have strongly considered it for the little bit more magnification. Lot of good reports on the Accupoints handling the SCAR 17 recoil.

Several hundred rounds through my Scar 17 with Larue Mount(s) No issues yet with my ACOG TA11H-308G nor with my Primary Arms 4-14. Both mounts have properly held zeros when switching from one scope to the other.

Wish they made a variant with the throw levers on the right side(Yes I know you can flip it) - Probably going to end up with the LT-745 10MOA. Also looking at the ADM Delta. From what I gather and have read, there are several others that had this particular issue with this scope and some say it was due to a bad adhesive used within the scope, or some kind of pin in the erector tube assembly failing. Seems other people are enjoying theirs. We'll see what happens once I get it re-mounted and back from Vortex. |

Grabbed a Trijicon AccuPoint 2.5-12.5x42 with the Bobro quick release. Only have 300 rounds through it thus far but no problems as of yet. Trijicon said they'll stand by their product and if problems arise will repair. Had an ACOG in for repair about one-year ago and was promptly repaired and sent back (not related to the 17s beating it up). I have full confidence in Trijicon. Just didn't have the funds for anything else so settled on what I could afford and I have to say I'm happy at current time.

Maybe buy 30mm rings, then use a 1" polymer adapter for a 1" scope to help absorb the shock.

I use both the 30mm and the 1" scope rings with the inserts on almost every weapon I scope. They work well but the SCAR 17S has a little different recoil than most weapons due to the bolt weight and forward impulse so it takes a much better made scope and also a very good set of rings/QD mounts. For both of mine I use Seekins 30mm rings. |

I have thought long and hard about what optic I am going to mount on my 17. After really being honest about what I was going to do with the rifle, how far I am going to shoot and the fact that I really love my ta31FG on my go to AR, I am going with a TA11. I love the light weight and simplicity of the ACOGs and to be honest, 3x to 4x is all I really need power wise. Don't get me wrong here, there is nothing wrong at all with big power optics or big money glass on a SCAR but I just don't need that much. On the other hand I never understood the guys who put a ChiCom made Primary Arms scope or red dot on a rifle like this. /my two cents |
