ARM.co low profile 71 sight set for AR-15
Solid sight package. Constructed out of very durable polymer, my guess , glass filled nylon.
I noticed initially that the sights didn’t seem to seat well at first glance. However, considering that they were new , I operated the opening sequence multiple times and found no evidence that they had not completely and securely seated. When ordering this sight set ,realize that they were designed not to come to a perfectly vertical position when fully seated.
Well worth the money.
Having spent untold amounts of money on sights/optics I had been unable to find a quality "cheap" set of flip-ups. Searching for a set for a "truck gun" was tough. Leary at first, I went ahead and pulled the trigger so to speak. I can say the search is over. Best set of polymer sights I've delt with. For the money, this is it. I was very happy and can say for sure another set of these will grace another of my builds.
I prefer these over Magpuls MBUS
These are as nice of a quality as Magpuls Buckup Sights. I prefer how these look on a rifle over Magpuls.
