Sliding stock for XM8 compact carbine

Click for bigger pic

xm8ccbutt.jpgA reader forwarded me this. An adjustable stock will apparently be offered for the compact carbine configuration of the XM8. Previous information indicated that a simple buttcap only (at right) would be available. (See this post for images of all models for comparison.)

As the reader commented in his message

I feel a little better about the shortest version now, it seems a better fit for rear echelon folks to tote around. I have personal experience with the MP5K and while it is more capable than people give it credit for (especially with practice, you really don’t need the shoulder strap if both of your arms are free and unencumbered) that is not the sort of skill level we can expect from the truck drivers and road builders and every other kind of rear echelon soldier.

This is a spot-on observation. I commented at the time that special forces and urban CQB fighters would probably have uses for the ultra-short submachinegun-like compact carbine, but the majority of these little things would probably be issued to vehicle crews and support personnel for self-defense. The sliding adjustable stock will make the weapon much more usable for the typical tank crewman or supply clerk.

The datasheet I snagged the image from indicates that the length of the compact carbine with buttcap is 21.1″. The length of the compact carbine with the sliding stock is 26.8″-29.8″. So apparently the butt doesn’t slide the entire length of the rod it’s mounted on. The length of the baseline carbine with stock fully in is 30.3″. By comparison, the MP5K (the super-short version of the HK MP5) is 12.7″.

The sender notes that he found the link on and that the image comes right from an HK release. Good stuff, and much appreciated.

Keep those cards and letter coming, folks!


  1. Well this gun if you ask me is a little queer for the gun hoe americans if you ask me. are all you guys turning gay cause it looks like it to me. with your stylish tan colour to match your desert storm uniforms and your clear ammo clips that throw a little bit of pazazzzz in to it. how about your soilders go in to battle showing spirt fingers while there at it. your a bunch of HOMOS war is about killing not who look stylish while doing it. Now your soilders can toss the salads of the captured iraq’s with style good job AMERICA.

  2. Dear Mr Robo-Serb, I assure you an XM8 will kill you just the same as you have killed the English language! By the way. You got a brother named Homo-Serb?

  3. Dear Mr. Robo-Serb, Please go to Iraq, and please fight against us. I can only imagine what would happen.

  4. This is the new weapon our troops need now with the 6.8 ammo. and give the old crappy m4s to the Iraq Mil. This unit can be updated later for the 20*25mm exp rounds when they get the kinks out.

  5. The M16 was a problem in Vietnam when my brother used it for two tours and, from what I hear from vets in Panama, Iraq & Bosnia, it is still a problem. As a former firearms dealer (FFL), I received a lot of trade-ins in Colt and third party manufacturers of uppers & lowers of both the M16 and AR15 families. Not all, but the majority, had problems and I had a ex-mil armorer work on them. I experienced problems in American dirt & mud where a side by side matching with a Galil (AK47 variant) did not. I’m not a field test expert, just hard on firearms and vehicles year round. I used and abused both in forest, desert & tundra without the hell of somebody trying to kill me. Field what the troops need. Don’t wait for the next big thing down the road. Tomorrow never comes today. Put in interim solutions to phase out the bad and put in better. We’re supplying other armies (allies) aren’t we? We don’t have to crush the old stuff, just take it off inventory and cycle it to other nations who don’t have enough. My two cents.
