KAC appears to disagree with you: http://www.knightarmco.com/commercial/?term=sr-15

There are two dimensions to “high end”: The quality of the base components and the additional features/capability more $$ brings. Most consumers would expect to get both on a high end product.

I agree that quality of components constitutes high end, but additional features and capability mean squat if those features are attached to a del-ton or doublestar. KAC is not the only tier one AR on the market, it is only one. Pretty sure that Noveske and Larue are top notch, neither of which have the coveted ambi- selector high quality component.

Gunz, why do you prefer the Geissele rail to the NSR? I really like the look and feel of the NSR on a Noveske I handled, figured that would be my next rail but I lave not handled the Geissele. I cannot imagine what could be inproved over the NSR which looks lighter.

Ranier: https://www.rainierarms.com/?page=shop/detail&product_id=2888

I can find more examples.

At a minimum, KAC, Noveske, and Rainier believe that an ambi selector is a worthwhile standard component for some of their more expensive AR-15 products. As the OP said he wanted to put together a high-end build (and supported it with a credible component list) I offered the suggestion of an ambi selector. I’ve provided supporting data for my “ridiculous” suggestion. Can we move on now?

As IG says, contact whoever you are buying from and make sure… as far as I know, the newer MEGA uppers have the index pin hole, as do the Vltor made Noveske MURs.

Anther option is the RA Upper, it has the index pin hole as well - https://www.rainierarms.com/?page=shop/detail&product_id=1611

Did some Internet searching and it looks like ADCO can drill the hole for the NSR on any receiver.

That RA upper looks like it could be a good mate to the NSR rail without having MEGA stamped on the side. Would be nice to keep the mutt look to a minimum. Looks like the seekins lower with that RA upper could be the ticket.

I think anyone with good common sense, a center punch and sharp drill bits can carefully measure, mark, punch, start with a small drill bit and step their way up to the correct bit to drill the shallow hole needed for the NSR anti rotational pin. By taking your time it would be an easy mod.

I’m not convinced that the index pin hole for NSR is necessary. I have a lot of rounds and a fair amount of abuse on my SBR with NSR and no hint of misalignment. Before the NSR, that rifle had a DD Lite on it for a few years, also with no anti-rotation pinning of any kind.

There’s more to the BADASS than just being ambidextrous, and I agree that it represents a real step up from your typical LPK selector.

In addition to the usual roll-pin starters, and roll-pin-specific punches, two invaluable tools for building an AR are the Hammerhead tool and the Geissele Reaction Rod.

I’ve handled but don’t own the Geissele rail. I like it, but I don’t see any advantage over the NSR.

OP be aware that many or most crowfoot wrenches are too thick to work with the NSR nut. I bought a cheap Sunex and spent about 5 minutes with a grinder to get it to work. Simple to do, I’m glad I didn’t spend the money for the SnapOn. I’ve heard rumors that the Noveske crowfoot is a little lacking in the robust-ness department.
