Flush Cup Placement

[kmc0929]

Realizing that the flush cups that came with my A5 (underneath the stock) aren't very useful, especially if using a bipod/podloc. I'd like to put some on the side of the stock. Does anyone have any suggestions / factory measurements for placement?

Any suggestions for a smith to do this? I'd like to have some confidence that I can tug on these and they not come out. Id like to send it back to McMillan but I am sure the wait would be crazy.

It doesn't really need to be some exact measurement, just find a good spot and see how it will support the rifle. If you think it through and only drill once, you'll be fine.

Re: Flush Cup Placement

any suggestions for a local central NC guy who can do this? Id like to have these cups be as strong as the factory ones, and my skills probably arent going to cut it.

***The more I read about this the more I feel like I can do it - maybe thats false confidence... What is it that McMillan would do differently / better than me if I sent it to them? I assume they use the Grovtech cups and Marine Tex?

My GAP Crusader came with 4 flush cups in an A5, 2 on the bottom and 2 on the left side. You can see the side cups in this picture. The front cup is centered 1 in. behind the bipod lug and about 3/4 in. down from the top of the stock. The rear cup is centered 1 3/4 in. from the rear of the stock (not counting the recoil pad) and about 1 1/8 in. up from the bottom of the stock. Hope this helps.

I would think a rear flush cup mounted towards the bottom of the stock would be bothersome to carry slung. Mine that came more centered from McMillan is still bothersome. Point being I would get the flush cup mounted as high as possible to tame the rifle keeping the scope from flopping around while it is slung. This is what I did on my current McMillan.

I added flush cups to my A4, and the reason I put mine low where McM puts theirs is because I run a stock pack. If it was any higher on the stock it would be covered up and become useless. I'm not sure if this is why McM puts it there, but it's why mine is there. I don't have a problem with the scope moving, but there is only one way I can sling it over my shoulder.

I'm not sure about the McMillan composite construction but I mocked up a simple threaded Grovtec flushcup in a piece of 1/2" thick x 2" wide walnut. Bridging a couple saw horses a single cup suspended 90lbs without pulling out. You shouldn't have to worry about the cups being "strong" if you install them with appropriate epoxy or threaded variety.

Location's not too critical either. Look for examples by the professionals and imitate them. Or get yourself a $50 take off stock and start drilling/tapping/glueing and find locations that work for you. Of course you could also honeycomb your stock and have dozens of options for sling attachment. The cups themselves are pretty inexpensive, just call Grovtec.
