Questions & Answers
Are these aluminum or polymer? Expert Answer

These are steel.

by Ethan C., Gear Expert, May 3, 2019
Are these spring loaded

These sights are not spring loaded. The front sight has ergonomically ‘scalloped’ indentations to facilitate fingers easily grasping it to manually (required) raise the sight into shooting position. Both front and rear sight lock into position when manually raised.

I have ran these on a MK18 clone for around 4 years with hard use. These sights are nothing short of excellent and my go to if I’m not running scalar works or Daniel’s fixed irons. Just purchased my second set for my Sig716i.

Sig Backup Iron Sights by Schak, May 12, 2018
These sights are solid and durable. They are easy to mount and definitely a good value. I looked for many different sights and these really stood out in terms of value. Don’t overpay for Magpuls when these are a viable option.

Nice iron sights by Fattymunchkin, November 5, 2018
I bought these Sig Sauer flip iron sights because my new Sig Sauer 516 did not come with any sights. Although I also have a red dot, I still wanted to have iron sights on my gun. They are very well made and are very easy to install.
