*Open bolt configuration is also availble with the Styer AUG, Colt M-16, and of course the M-249.
The Lage offering is absolutely reliable, and I feel the quality, engineering, and thought put into this is equal to his other superb offerings. First rate! Personally, I don’t find a need to add all manner of high drag, low speed gadgets to the majority of my guns. I have Magpul BUIS on two of my uppers, but those are the primary sights for blaster uppers. They aren’t back ups. Maybe I’m the only guy who fails to see the need for back up sights on a gun that will never see use beyond burning up ammo. Battery failure? Please! Can you not keep a spare in your range bag?
I currently own three Holosun optics including a pair of 503s and a 510. I like them a lot and find they’re comparable to the four EOTechs I own. To be clear, I’m a circle dot, doughnut of death fan. So far I feel the Holosuns are long on value for short money. If you feel the need to spend two, or three times on an optic, have at it. I’ve seldom been disappointed with spending more on high quality products.
Slings have a purpose beyond simply carrying a rifle. Will you actually use it or is it something that’s in the way? You have to make that decision based on how and when you’ll use it.
A light? Why? There’s a great three gun match in town that shoots in the evenings during the summer heat. Lights are a definite requirement, but beyond that? Will you be hunting hogs at night? What is the intended use for a light on the 11-15? How often will you be using the light?
While I don’t own a MAX-15, I do have a RR M-16. I’ve found no reason to go full on ATAS by adding BUIS, slings, lasers, lights, bipods, off set sights, cup holders, laser designators, etc. to most of my uppers. Just because it’s got rails doesn’t mean you need to cover them with useless stuff like back up lights.
