| I just switched to a commercial buffer tube today(from my mil-spec, so my ctr would fit) and now i can hear the spring in the tube when i cycle the rifle. Is this normal? |
which means it would have worn off eventually and started making the springy noise....if you really wanted to try to eliminate it you could get a can of that stuff to refinish USGI mags and spray it in there. |
Nothing a little google couldnt fix. www.midsouthshooterssupply.com/item.asp?sku=0001240131 something like that? |
Like the buffer tubes? Mil ones are a little wider, and have better threads apparently. ANd its forged. Where the commecial tube is cheaper. |
Only if you want to be able to use milspec stocks. One isn't "better" than the other. It doesn't really matter if you're happy with what you've got, but if you want, say, a SOPMOD stock, you're going to have to switch to a milspec receiver extension. I had a commercial stock on my Bushmaster for years (it came with their old aluminum one), and it served me well. I only upgraded to a milspec tube recently. If you have more than one it makes sense to standardize them. Some manufacturers make their stocks both ways; others don't. Oh, and be sure to stake that retaining nut so you don't get jumped on by the nit-pickers. |
Thank you, Pat. I felt that the commercial tubes would actually be stronger since they are, in fact, thicker, but I didn't see that as a selling point. If the milspec versions are stronger, then that is a Good Thing. It isn't what caused me to switch, however, and I'm not really concerned about what others may "clearly" think. The fact that I did change should be good enough. It's good enough for me, as now my options are not as limited. Stronger too? Well, that's a bonus I hadn't counted on! I guess I win either way.

It is stroger because on the mil receiver extension the tube is machined to a smaller size, but the threads are full dimension. It is not that way on the commercial ones- the threads are not full size. Think of this from an economic standpoint. Those companies that supply DoD have to build to a standard (the TDP). Aftermarket companies don't. They do that not to make a better gun, but a less expensive gun. It is cheaper and easier to make the commercial one. The threads on a commercial receiver extension are not full profile and have a lower percentge of engagement. |
OK, fair enough. Makes good sense to me. At any rate, I've made the switch, and have no further use for my commercial stocks (except perhaps to make some tactical toys for my young son). Thanks again
