Real-World Testing: Putting SI AR-UL-MFEP&ACN-FDE END PLATE & ANTI-ROTATE NUT to the Test
First Use Experience
The first opportunity I had to test the SI AR-UL-MFEP&ACN-FDE END PLATE & ANTI-ROTATE NUT was at my local outdoor shooting range. I installed it on my primary AR-15 rifle, which is chambered in 5.56 NATO, and ran several hundred rounds through it, focusing on drills that involved transitioning between targets and using a sling for support. The installation was straightforward with the proper tools.
The weather that day was sunny and dry, so I wasn’t able to test it in adverse conditions right away. However, the improved sling attachment points felt much more secure than the standard setup. I experienced no issues with sling twisting or binding.
The installation was straightforward, thanks to the included instructions and the intuitive design. I did not encounter any snags. It was a much better experience compared to previous end plate replacements I’ve done with cheaper parts.

Maintenance has been a breeze; a quick wipe-down with a lightly oiled cloth after each range session is all it takes to keep it in top condition. It outperforms the standard end plate and castle nut setup due to its robust construction and enhanced functionality. I will definitely purchase again.
