Jun 12, 2021 · I sold a URGI with a 10.3" barrel and have an MK16 with a 11.5" barrel and an MK18 RIS II with a 10.3" barrel. The 11.5" barrel MK16 has more M-Lok slots than the 10.3" URGI and feels really good. It has the large top tab keyed to …

Jul 4, 2018 · My personal preference (and many others) is a second focal plane lpvo on an AR. Also, the ACTR's reticle is far too busy for me for a 14.5" rifle with an effective range of only 500 meters. I find a quality second focal plane lpvo with a clean reticle much more practical for a M4. The Vortex Razor, Kahles, and Steiner fit my preference much better.

May 18, 2020 · I have urgi 10.3" and its a nice rail but i dont think its worth what G wants for it especially since its not a exclusive clone piece and you need a very low profile gb to clear the rail , mine has a G gb and theres not much room but thankfully the 10.3 is stiffer and dorsnt flex as much . Your ris II is a stronger rail just not as thin.

I later picked up a Razor 1-10 for my URGI, kept it for a bit and sold it. I recently picked up another Razor 1-10, kept it for a day and went right back to my T2 on the URGI.

The SOPMOD blocks reference the included handguards, optics, lasers, etc which accompanied those improvements. "Block 3" is more like a turn of phrase to include the URGI currently being fielded by USASOC.

Feb 7, 2023 · You can see the lower was most likely updated from one marked "M4 Carbine" to "M4A1 Carbine". The second picture gives the most detail of the receiver roll marks. [ARCHIVED THREAD] - FN in the wild (Mk18, M4, M16, EOD, Sopmod, URGI, etc)

Dec 31, 2020 · Experience with G: a URGI, an 11.5 SD upper, and a complete 16 SD rifle. The gas tuning is perfect (very soft shooting) even when suppressed with all of them, and the full rifle has super nice controls: charging handle, trigger, bolt release, ambi safety, etc.

Sep 20, 2024 · Lastly, I’m wanting to get a LPVO in my mix somewhere to be able to stretch an ar type rifle once in a while and the URGI seems a good application. I am considering the Primary Arms 1-6 x24 SLx. I like the reticle, i like the magnification, and I like the red dot capability as well, but mostly the reticle. So, my question is this
