I don't want to hijack anybody else's thread so I started a new one. I have a Del Ton Sport and I want to change the commercial buffer to a mil spec buffer. I'm not sure why they went com spec buffer and that's really the only thing that bothers me about the set-up. Everything else works fine for me. My question is what mil spec buffer should I go with? (H1 or H2 etc) I mostly shoot PMC (.223 & 5.56) and I don't want to create any feed issues. I'm guessing that this (see picture below) is a semi auto AR15 BCG. I have no idea what the buffer would be comparable to now. I have a feeling it's over gassed. The brass hits the deflector with some force. Any input would be appreciated. This is my first AR and I'd like to learn all I can from it before I look at building my next one.

Change the tube you will also need to change to rear stock. you dont mind the extra cost?

No, I would be buying a stock kit.

There is absolutely no difference in the performance between the two, all mil-spec means is military specification, it doesn't make it better. It's just the way that they do it. Changing the tube and stock is little more than a waste of funds.

Good to know. So here's another question then. Do they make different weight commercial spec buffers? If its over gassed can I go with a heavier com spec buffer? Are com spec buffers still marked H1, H2 etc?

Exactly...

If anything, the commercial tube is stronger because its thicker.

The inside diameter is the same between com spec and MilSpec. A heavier buffer could make your gun run more reliably, but if it doesn't need it why spend the cash??

I am fairly certian that there isn't a commercial only buffer, I'm almost certian that they all work, but I would double check with one of our AR15 experts here.

Despite the name of the 'brass defector', your casings should never touch it, a heavier buffer moves your ejection point forward, alleviating the problem. I've been meaning to get a heavier buffer myself for this reason.

So if it ain't broke then don't fix it right.
Should the brass be leaving marks on the deflector? I seems like it's hitting it with too much force. (That's why I'm thinking it's over gassed?) Thanks for being patient with me I'm still learning the platform. :)
