Rainier Arms Back-Up Iron Sights

Rainier Arms has been aggressively expanding from being a high-end parts reseller to also selling parts of their own design (though typically made under private label). The latest product to the fore is their Rainier Arms Backup-sights, which are a set of fully machined ultra-low profile back-up iron sights designed for the high-end enthusiast.

The new sights are extremely low profile while managing to keep some practical features (unlike the Leitner-Wise utlra-low profile sights, which set a new record are true “low profile”). The sights are fully adjustable for windage and elevation, but only windage can be done on-the-fly.

The front sight is compatible with all standard M-16 & AR-15 front sight posts and is flanked by towers to protect the post. The rear side has a nifty stowage position for a peep sight, under the main battle sight. Both sights are finished black, with Rainier stating they are ready for maritime environments.

Pricing on the Rainier Arms Back Up Iron Sights is not for the faint of heart or wallet. The set retails for $249.95 and is available direct from Rainier Arms. From another perspective, pricing is not bad for for something made in Germany. Sorry, but not multi-axis function like the TUOR sights (which are incidentally more expensive)

    I have to ask: 250 for backup iron sights? are these that much better than normal back ups that go for like, 1/3 or less?

    • Anonymoose

      You mean like those plastic ones that melt on gas blocks?

      • Paul White

        my magpul mbus haven’t done that and they’re like 60-80 bucks

        • Anonymoose

          Did you mount the front sight directly to the gas block?

          • Dracon1201

            I did. Adams’s Arms gas block, and a Bushmaster DI upper. I’ve not had them melt, but I’m also not a Tier -23 Operator operating in dynamic operations across a variable spectrum of multinational latitudes and special missions. Polymer is always a trade off, if you think you can melt them, go metal and accept the tiny weight and price increase.

            Anonymoose, are you stupid enough to put plastic on a gas block ? please put down the ar and back away! Then sell it to someone responsible!

      … but but.. Germany bro. What part of “germany” don’t you understand. I bought some paper napkins for $80 because they were made in germany. Precision made table napkins.

      • That had me burst out laughing, I might just have to make that my new Facebook Cover picture.

      I would say no. Unless you use your irons with much frequency. I like the knights folding irons myself, but haven’t purchased them for several builds I’ve done over the past year, instead reverting the MBUS.

      It becomes hard to justify, especially if your optic is your primary means of aiming.

  • Well, I appreciate what they’re trying to do, but I’ll stick with some MBUS Pros.

  • I’m not seeing the value of these suckers equalling three Mosin Nagants, just not seeing it….

  • SD

    That’s half the price of a decent red dot for something used as a back-up. No thanks.

    These look almost exactly like KAC sights.
