When do we get an XCR pistol? ??? ??? ??? I've been building a couple of AR pistols, but it sure would be nice to have an XCR pistol!

How short can you reliably make the barrel?

XCR pistol? Just remove the stock, and voila!

As for barrel length, under the current gas setup, you will only be restricted by the gas valve and block. I haven't taken a caliper measurement yet, but I think somewhere around 11.5" is about as short as you can get it and still have room for threading. My XCR is one of the older ones with a 1/8 barrel. We cut and rethreaded it @ 12.5 inches. I went this length because anything under that would not allow mounting of my sound suppressor, due to it contacting the gas valve. I also has to play with the gas system some. I ended up opening up my gas port and block a little to compensate for the decreased dwell-time of the gas in the short barrel. YMMV.

As for plans for XCR pistols, I don't know of any.

we're going to do a PDW version eventually. The barrels will be 10", and the uppers will be cut short as well. Read around. You'll find the posts. :)

Terra, will the length of the PDW barrel be restricted by the gas block location? I would think it could be played with and get somewhere around 8", but I am no engineer.

I like spending my time NOT in federal pound me in the ass prison, so I think I'll keep the stock on ;D .

I'll search now for the XCR PDW, sounds like a sure buy though once it comes out!

I think what ExPara was trying to say is that by registering it as an SBR (and/or an AOW) and paying the $200.00 tax stamp (plus the 5.00 for AOW and possibly another $200 for mfg it as an AOW) you can
do what he is describing. Legally.

There, does that help?

If a receiver has ever lost it's virginity by mating with a stock it cannot be made into a pistol...easily.

If a receiver was always a good girl and did not fool around with those stocks that always keep trying to attach themselves, then she can be a real pistol! Easily!

No, it doesn't help one bit unless I want to buy another XCR and go through all of the trouble/time consuming process of making it an NFA item, not to mention the barrel would still be what, 12"?????


Oh well, I just bought an FS2000 and the next purchases will be the SCAR and ACR. If RA came out with a pistol (556 esque) I'd certainly buy one though. I guess a simple link instead of having me search all over the net would have been a better answer.

Any chance RA will ship a XCR pistol with the already existing 12.5" barrel? The engineering is already done. Just whittle a piece of aluminum to plug the slot for the stock and it is good to go. We can always upgrade to a shorter barrel later. I want to buy one before the election.

I am also wanting a handgun version as well but the 10 or 12.5 inch barrels are not what I am looking for.
I would just give them a call and see if a handgun is in the works or a future possibility.

The point is to get the pistol before the election. It can always be rebarreled shorter later as the serial number is on the correct place.

It would nice if they could make a 7.5 inch XCR Pistol.

If you use the method of buying a stripped lower you can build a pistol. Just like an AR, when you buy an AR reciever and want a pistol, you can do the paperwork as a pistol, and build it as a pistol. I would assume this would be the same for the XCR.

...not if it leaves the factory as a rifle. I don't know how RobArms designates their lowers with the ATF, but they are probably manufactured as rifles.

Also, even if that were the case, I would still have a 12" barrel on the upper. While I don't mind that, and it's certainly a good suggestion, it's not what I was looking forward to. ;D

There are pistol AK's, so cutting the barrel down to 7" and machining down the upper could be done at any competent machine shop. You'd have to fabricate a new gas piston rod.
To me the only hard part would be getting the location/size of the gas-port correct. Probly start with the AK & AR pistols for reference.
I know a local C2 manufacturer (he's has a C3 FFL and makes SBR's) that wants to play around with an XCR when he get some free time.
