Hey everyone...I'm new here and have a simple question. My experience has been with M-16s and ARs but I now have a new AR-10. I want to replace the standard A2 stock with a 6 position but not sure if it would require a heaftier 6 position stock than whats on the M4s. I'm pretty sure that the buffer spring is heavier on the AR-10s.

First, Welcome to the Forum. Glad to have you aboard.

Second, I moved this thread to the more apt AR-15 discussion forum as it fits a little better in over here. No harm done...

Now, as to your question - this is a gray area that comes up a lot, and quite frankly there are two sides of the equation.

Side A: Yes, you should have the large spring and buffer assembly because there is increased loading on said parts under recoil.

Side B: No, you can mix and match your buffer springs, as evidenced by some folks running 9mm recoil springs in their AR-15's.

Personally, I don't mess with what was designed in this case. The good folks who came up with the design, felt a larger spring and buffer was required. If they felt they could get away with out it, why wouldn't they have done so to save on production costs for the weapon?

My vote would be to order the correct size collapsible stock that you want, and it should come with an included spring and buffer.

Thanks for the info...I guess i was wondering if the ar10 buffer spring would fit and function in the M4 6po stock. I'd rather get one made FOR the ar10 but its hard to find them for under $150...

Well, that being the case, you could just get the measurements of your buffer tube and order one that has the same ID. Then you can give it a try and see for yourself. If the AR-15 one does the job, no harm immediately done.

But again, I personally would err on the side of going with the original engineering design for less wear and tear.

Really, when you think about it, all a lighter spring is going to do is allow more felt recoil and risk possible, and let me stress, POSSIBLE, damage to your BCG under faster than normal travel rates ( due to less spring tension ).

I am sure it will work and run, probably, just fine with a lighter spring. Some may even prefer it - but it's not for me personally....
