M4 parts

I have an M4A1 but was thinking about modifying it to make it a CQBR. Ive made a few modifications on it already (RIS rail, aimpoint & ACOG replicas, foregrip, BUIS). I was wondering does anyone know where I could get a short barrel from (and anything else I might need)?
Would an airsoft CQBR barrel make do??
Cheers

Also, in the past I tried to contact modelgunsworldwide about accessories but never got a reply. Is it possible to get dummy 5.56 rounds like the ones on the website here in the UK?

Usually you can cut these barrels down and re-pin them together at the right length , Airsoft ones are unlikely to be a direct fit .

hmm modelgunsworldwide ignored your email ...how impolite !

if you google on the net you should fine somewhere selling inert 223 rounds ...battle orders used to do inerts but I bet most of their stock is gone now ... my last inerts were from them a couple of months ago .

Cheers for the links Doc

Now, I doubt that my M4 will be able to cycle these inert rounds...?
modelguns worldwide suggests a dummy round firing pin...?

I didnt really want to chop my barrel down to make my CQBR, I thought I'd keep it and that way I could swap and change the look of my M4.

Hi Chek,

I'm sure Francky sells Mullbery Field Dummy rounds in 5.56mm. They'll be more expensive than inerts but I think you can cycle them through your M4.

Check with Francky either by PM here (he's a member too) or via his site:-

Regretably, Jay at Modelguns-Worldwide refuses to sell any accessory or spare parts to customers UNLESS the gun those bits are intended for was supplied by him in the first instance.
We've all come accross this by now I'm sure. I spent a lot of money at Modelguns Worldwide when I first discovered the joys of modelguns and was more than as little dissappointed to be refused a magazine for a gun I bought privately
That said, the service I recieved for guns he supplied was great...
I would've probably bought more off him if he'd sold me that mag' but there you go

The " dummy firing pin " is a just a bit of brass rod turned down to help the 223 rounds seat properly in the chamber once the detonator pin is removed.

Simple enough to make one of those up .

The rear of the real 223 round is 9.60mm and thats the same as the CP cartridge so inerts should fit into the bolt head no problem and the chamber is deep enough to take the 57.40mm length of the inert round .

Only real problem you have is the added plate in the front of the mags ..that prevents full sized rounds being fitted but its only spotwelded in .
