Questions & Answers
Will this fit on a Springfield armory saint victor ar10? Expert Answer

The Guntec USA AR-10/LR-308 Ejection Port Dust Cover Assembly should work with the Saint Victor AR10.

by Hunter, Gear Expert, September 6, 2022
My upper is AR-10 from Bear Creek Arsenal. Will this work? Expert Answer

Yes, the dust covers and hardware for them are universal on the AR-10 platform. They can fit both DPMS and Armalite pattern rifles, so this kit should fit your receiver.

Guntec dust cover by Pete, Verified Owner, March 14, 2018
This fits well into an Aero M5. Easy to install, letters on both sides, so you see it when it's open and closed. Only reason no 5 star is that the spring was a little weak but works non the less.....

AR-10/LR-308 Ejection Port Dust Cover Assembly by Craig, Verified Owner, June 13, 2018
The AR-10/LR-308 Ejection Port Dust Cover Assembly was just as advertised. it installed without a problem and it works on the DPMS LR 308 Upper receiver without a problem. And it looks great, the only issue is that it didn't come with a clip.
