    Noveske Receiver Extension / Buffer Questions

    I recently purchased a used Noveske N4 10.5" SBR from a local seller. Come to find out, the previous owner had swapped the original mil-spec buffer tube with a commercial one in order to fit a Magpul ACS-L stock he had on hand.

    My first question is should I be at all concerned about the "at home gunsmithing" or the fact that the rifle now doesn't have the mil spec tube? Should I not sweat it, or switch it back to mil spec?

    Second question: Is there any way to identify which buffer and spring is in place? Previous owner says he had swapped out the buffer for a heavy one because m855 ammo was having cycling issues. But, the buffer that's in there doesn't have an "H" marking.

    Thanks!

    You can weigh the buffer or get a hammer and punch and tap out the roll pin holding the buffer together and take a look at the 3 weights inside. 1 tungsten and 2 lead = H.

    Spring is harder to identify, but unless you see colored spray paint on the front of it, it's probably a regular carbine spring.

    Is the castle nut staked? If not, it's like a 5 min procedure to swap it back to mil spec, but not worth it unless you plan on changing the stock.

    For a piece of mind and a far better stock/RE tube/buffer/spring you can spend the money and do it up right. http://www.gandrtactical.com/cgi-bin...ategory%3DB5SY

    Currently, the castle nut is not staked. Going back to a mil-spec tube would be for peace of mind, if it's worth it?

    There is absolutely no need, it has zero influence on functioning as far as I've seen. If you like the current stock, don't waste the time and money to swap it.

    I think it would be worth it in the long run.

    My opinion of course; it would be easier to change the current (unknown) parts out for good quality (known) parts. You out them on yourself, you know what's gone into your rifle and you know it was done right.

    I don't use retard parts on anything so I would go with a milspec tube. I also doubt that he knew anything about buffers or anything else. If Its unmarked who knows what it is or where it came from.

    As to buffers, they are generally marked H, H1, H2, H3. If there's no mark, it usually means carbine. What cycling issues was the owner having? The reason to swap for a heavier buffer would be overgassing and whatever problems that causes. If it's short-stroking or otherwise failing to feed, the solution would be a lighter buffer.

    You say the current buffer has no markings. That makes me think that the original owner was having FTF and tried to solve it by going from the stock H2 buffer to a carbine buffer.

    If it were me, I'd return that Noveske rifle to its original configuration...milspec buffer tube, H2 buffer. I'd also give the BCG a hard look...make sure it's OEM and that he didn't replace it with some other version. One can generally be pretty confident that any rifle leaving Noveske will function well. If it's been diddled with subsequently and it has FTF issues with M855...you gotta wonder why.

    Thanks all for the input. I'm very tempted to go with the package AKdoug provided with an H2 (or H??) buffer.

    The previous owner stated he "added the heavier buffer for faster bcg action." He put the heaver buffer on because "when shooting m855, the lighter one wouldn't cycle as quickly and cause a misload."

    The 10.5" upper and n4 lower were originally purchased from Noveske separately. Perhaps the lower came with a buffer meant for a 16" bbl, and he needed to change the buffer to work better with the 10.5"??? I'm just guessing...?

    Also, the BCG does look to be authentic. It has the "N" stamping.

    There is no H1 buffer. The H buffer is H1. The order is carbine (plain), H, H2, H3.
