3. Secure with screws (included), tighten to spec.

4. Re-zero your iron sights before range use.

???? Common Issues & User Experiences

Some users report that the retention tab (or lug) on optic plates might shear or embed into the slide—especially during zeroing. This appears to be a weak point in the design. bularmoryfirearmsusa.com+1gbgunsdepot.com+1reddit.com

“The little tab at the bottom… has completely sheared off… embedded in the slide” reddit.com

Another user on Reddit emphasizes that BUL Armory’s customer support was responsive, replacing the plate promptly—even though the tab issue occurred with minimal range use. targetzone.eu+15reddit.com+15reddit.com+15

???? Compatibility & Aftermarket Options

• The cover plate is intended for specific UL models; it won't fit standard UL optics-ready slides.

• For those seeking red dot compatibility beyond RMS‑c (e.g., Holosun, Trijicon SRO), adapter plates like those from Toni System ("Type B") can work—but they don’t include iron sight provisions. reddit.com+7hunting-trade.eu+7reddit.com+7

???? Final Thoughts

If you own a BUL Armory UL or UL-Viper with RMS‑c optic cut and prefer the flexibility of an iron sight option, the UL Cover Plate is a solid addition to your setup. Its all-metal build and precise fit make it a durable solution—although the retention lug has been a pain point for some users.
