Hi all,

I am starting down the long (some might say frivolous) path of building a dmr from an AR base. This is my first AR build and from what I have heard M4 hopup units are... well somewhat awful and I was wondering in anyone had ever built a different unit that fits in an M4/modified one be similar in design to the ones we use in bolt-action rifles.

(if not Ill probably use a prommy neo unit)

thanks all.

I have the Prommy Strike NEO unit and it's very solid piece, I like it so far and it keep the setting for quite some time.
The only drawback is that it requires some parts from your old hop up unit, I had a spare CA hop up unit and thought to use that instead my stock SG Barrett but the gears didn't fit!

Not a major problem but keep it in mind.

Use a TDC setup, through the top of the receiver. That helps a lot.

There are Prowin CNC TM M4 hop up chambers for sale somewhere on the net. If you can't find those, a company, most likely Chinese, cloned it and is now selling it as well. I can't remember the site off the top of head though. :/
If you can't find the Prowin ones, there's also the madbull ultimate hop up.

Lonex (I think) is what you are talking about.

Yeah the TDC setup looks promising, where is the best place to read up on it?
