Customer Ratings & Reviews
A.R.M.S #71L Series AR-15 Sight Set
A little tight to get on, I had to use a rubber mallet and trim a small bevel on the front sight base. But they should stay in position well. Now I just want time to go shoot.
Best AR-15 flip up sights for the price
Why pay to much for a 'backup' sight that are used rarely? These sights fit and perform flawlessly! A Excellent set of AR Sights!
ARMS 71L flip-up sight
I like these ARMS 71L flip-up sight. They open easily and quickly. The short or long-range apertures stay put. More useful than the Magpul sights by far!
A.R.M.S. #71 BUIS
When comparing these sights to the MAGPUL BUIS it is apparent that the MAGPUL is a superior design. The A.R.M.S. sights have exposed moving parts and exposed retaining pins. There are too many sharp edges that can catch on clothing and equipment. The rear sight aperture is flimsy as the peep sights do not lock up. The retaining assembly that holds the sight in reserve does not lock up properly resulting in the sights flipping open when bumped or from recoil vibration. These are not hard duty sights and are not worth the money. I can say that MAGPUL sights, you put them on, they have a good positive lock-up and the are easy to zero because they come with the sight adjustment tool. The edges are rounded and any moving part is housed in an enclosed retainer.
Great Sight, works well with my eotech.
arms 71l series
i havent had alot of shooting time with them, but i think they are a nice setup for the money.
ARMS front/rear sigts S#71L
Works great, good combo.. would recomend this product
They installed super easy and flip up with authority when activated. Can be used in conjunction with red dot if you wish to use both systems at the same time.
very well made. strong. great fiber optic front sight
For the money cant beat them. After install almost right on target minor adjustments needed. Like the double apertures they are nice.
They look great and seem well built! I just wonder after heavy use if the release will become loose? Overall I'm happy and price was reasonable I would buy again if I build another rifle!
The shipping was great. The product is alright. I have a 870 wilson tactical 20" barrel with a Aimtech Warhammer, and this item is the icing on the cake. Had no problems mounting it to my shotgun at all. Its just a perfect fit to tactical shotgun. I don't care what anyone says, this sight is one of the best things I bought for my 870. Good quality.
