BUIS suggestions?




So...... I built this here AR lower from a few bags full of RRA components.   The Spikes Tactical upper should be here in a couple days.... complete but for one thing.  A rear sight.

The upper has a standard AR front sight, which I favor.  I plan to plant a spare Eotech 512 on the receiver, with a folding BUIS behind it.  I'm hoping for a good co-witness there.

So far, I'm leaning towards the Magpul  MBUS, but I know there are folks here who are WAAYYyyyyyy more knowledgeable than I.

Suggestions?

(Oh..... and more reports are in the pipe regarding the Liberty Ammo and the Doubletap pistol.  It takes time!)

Got them on 2 of my rifles and they are solid for their intended purpose....should work for you.....I personally don't like the "long range/small" aperture for it as a true back up I still have the carrying handle with sight and on this I would just need something to make torso hits out to 200 meters or so...but that is a minor gripe

I use the A.R.M.S. #40L on all my flat-tops. Fully adjustable and rock solid, yet small enough to stay out of the way when not needed.

Please don't rely on plastic sights. The magpul sights that you mentioned have been known to crack at the mount and fail.

For a folding sight that can work through an optic, I'm partial to YHM folding sights (and prefer the 'hooded' front, the sight wings are round and that helps me with target centering).

I have an A.R.M.S. 40L on my RRA 1st gen Elite Comp (though it doesn't get any real use anymore as that's now turned into a dedicated varminter). It's completely under the Millet TRS-1 mounted above it no problem, so it stays just in case. I have the BCM branded Troy built Flip-up Battle sight on my other AR. I plan on co-witnessing with a Eotech 512 at some point when fundage allows...

You might want to look at the Magpul MBUS Pro. Made of steel, yet surprisingly light - and very durable.

Thanks for the suggestions!

I favor the diamondhead products but they are spendy.

I know this is not what you asked, But I'll throw it out for discussion. There comes a time when modern technology advances so far, that hanging onto the older tech as a backup becomes just extra weight and cost. It happened for the 4 engine plane on cross Atlantic flights. I propose that the BUIS is such a device. There are so many good reliable optical solutions for an AR, that is no longer makes sense to keep investing in a BUIS. Asking about the BUIS is like asking who makes the best steam whistle for my car.

Just my thoughts. I use 4x ACOG (no batteries). If it breaks off or gets shot all the way through, I'll pick up one of my other backup weapons, with it's own sight.

I like the Magpul BUIS. Have them on three of my rifles.

A good alternative scope, that doesn't really need BUIS, is the Vortex Viper PST 1x4.

It has a lit reticule as well as a black reticule when the battery fails or is turned off (2032 battery). On 1 power the scope is a 2 eyes open scope.

Just my thoughts
