Can you tell I like bullpups?

[2nd Ranger]

Nope, I know for a fact he custom built that from scratch

[Star_folder]

So you're the one that got the Reece rifle on ASF! I wanted that!

Nope, I know for a fact he custom built that from scratch

What 2nd Ranger said. This gun was completely custom built. Though now I'm kinda curious what rifle you are talking about...

[2nd Ranger]

Click me!

I do believe he is taking about this ^, I must say there are some similarities

[Star_folder]

Yeah, I saw it. Similar, yes, but mine is still better.

[2nd Ranger]

well duh... Of course yours is better

yours can actually take advantage of that very sexy scope you have on there

[Hatch]

That M4 makes me feel good in funny places

I think that's about it. I do plan on replacing some of the ACM stuff with actual Magpul stuff. I quite like what they are doing with their company, and want to support them. Also the colors matching a bit better, and higher quality of materials does make a difference.

Also considering switching out the ACS stock for an Emod stock. I need room for that battery, and I think It might fit better with an Emod stock than it does with the ACS. Thoughts? Opinions?

[Romba]

I am blown away by all the time and effort you put into this stuff. It's awesome. Yeah, I kinda don't like the battery pouch, I think it'd look better with it in a stock.

[2nd Ranger]

I just happen to have an Emod stock you can try out Kory and see how you like it. It's even in tan.

[Echo1 Operator]

All of that work and you didn't put a gas block or gas tube on it. You won't really gain any battery room over an ACS with an EMod stock.

[Star_folder]

hmmm, I guess I could put the gas block and tube in.

[Echo1 Operator]

It looks stupid without it.

[Bishop]

[SteevoLS]

I do have to admit that it looks odd without a gas tube.

All the same... berry nice.

The purpose of this build was initially to replace my 417. With the flaws in it's design, it was unable to last with the demands I was putting it through. Thus, I needed a gun that could feed that fast, and not fall apart. So, I decided on an M4, and I wanted that M4 to be the exception, something that was perfectly what I wanted from an M4. And this is it.

During it's build, I decided to opt for a FT over the Lonex motor I was using, primarily due to the heat that 44rps was causing. With the FT, everything slowed down quite a bit. Initially, I wasn't too happy with the slower gun, but with a 14.8v, I was fine with it. Soon, I shifted to 11.1v, simply because I didn't have to wind the mags as much (lazy, yes I know).

I balanced the barrel to have it ported perfectly for .40s, as this gun is going to be my backup for OP: Sovereign Fury in August. Slightly over volumed for the .32s I usually use in the system, but I'm happy with it. The gun is a laser beam, and I have no problem nailing people. Range is currently unknown. Before I finished the hop up, I had a rough right hook on the ER-hop due to an off center nub that was quickly thrown together the night before. Now that it's centered, and properly applied, I need to test it's max range. I suspect it to be easily 300ft, as I was almost out that far before the gun was slightly off. At least now it shoots straight without me cocking the rifle to the side.
