Customer Ratings & Reviews
Best flip-up AR-15 sight
Best flip-up AR-15 sight available! The Knights are a little easier to adjust elevation, but this sight is built to last and every single detail about its construction is highly refined. Worth every single penny and completes my matched set.
ARMS Quality is spot on. Very nice packaging arrived on time. This company makes Quality AR-15 Sights that are much better than some of the other big names at a higher price. They are not the most compact, but they are exceptionally well made.
Super lite and durable AR-15 sight mount
Amazingly light and great quality AR-15 sight. I already had the rear and was missing — front sight. Very detailed and build like a tank. I know they are a bit pricey, but if you want excellent quality and unbreakable like sights, these are for you. Solid lock up when in the up or down position. You won’t hear these rattle at all.
ARMS 40L-F front AR-15 sight
The low profile flip-up AR sights are very good for storage in a safe box also easy put the whole rifle into the case carry much quick and pull it out much faster.
arms 40l front sight
I bought the ARMS 40l - AR low profile sight set, and I have to say these are the best sights I have used so far. They are exceptionally well machined and well manufactured. The hold-down is very tight, and deployment is fast and firm. I am using them as a backup for an Eotech Holosight. The sights look like they belong on the AR platform and bring that tactical-military look. I highly recommend them to anyone looking for backup iron sights.
great quality AR Sight
The ARMS #40L-F is amazingly lightweight and great quality sight. I already had the rear and was missing a front AR sight. Very accurate and build like a tank. I understand they are a bit expensive, but if you want great quality and durable sights, these are for you. Solid lock up when in the up or down position. You won’t hear these rattle at all.
Like all ARMS products, well made and designed
