Here's a different twist: what would you change on your XCR to make it the ultimate black rifle? A lighter 18.6" barrel? A folding/collapsible ACR-SCAR style stock? A lifetime supply of loctite...? (kidding, kidding...)
...you have to question why the rifle was designed to operate by direct impingement rather than by piston. Its not like piston rifles were not around when it was being designed. Hell, the russians made the AK with a piston system, and the russians aren't exactly engineering geniuses (hello Chernobyl). A lot of the early teething problems of the AR were a direct result of that design choice.

...Now, a lot of newer AR's are designed to be piston driven, a good change, but it doesn't change the fact that the original design choice was not the ideal one
What I would change:
-Making the front pin easier to remove and replace the small and easily lost clip by another system...

The nonsense that gets posted on this site is better than ever.
This is not to say its a bad rifle, its just some of the design choices are questionable.


Perhaps you could email or write Eugine Stoner and try to school him in firearms design.![]()

WTF?? again what does this have to do with XCR...Since Stoner isn't available, maybe ask Reed Knight about why the direct impingement system is 'questionable'.
Maybe he just needs someone to tell him that all his SR-15 and SR-25 guns are made with out of date and questionable engineering.
Let us know how that goes.
Funny, I don't seem to have these pissing matches with my shooting buddies, we just shoot.
My major concerns lie with the basic things about design. To me, they came off as half-assed solutions to get the rifle out the door. I can envision the designers at Robarm sitting around and saying, "Ah f**k it, that will be good enough, get it out the door!"What would you change to make the XCR the ultimate black rifle?
If you didn't get so excited and defensive, most of us "haters" probably would have ignored these threads long ago. Instead, it's just too much fun.This is true, however, there are not a handful of people who pursue every mention of either on this forum with an unending desire to attack them.

- "Hair Pin" spring clips holding the trigger components in. They are too fragile, mine failed after 50 rounds. I would have preferred something stronger, "E-clips" would have been better. Some with the front pivot pin.
- The barrel retention system. A single bolt interfacing with a divot in the barrel just doesn't sit right with me. It's not a symmetrical force and is too easy to misuse and launch the barrel (like the M96). Something that actually pulled the barrel back into the trunnion would have been preferred.
- The folding stock. No positive means to hold the stock in the folded position. Numerous solutions out there that could have been done.
- The shell ejector. Almost seemed like an after thought. As a by-product of the design, the bolt carrier with a big slit down the side also bugs me. Undermines the structure integrity of the whole bolt carrier, in my opinion.
These are my opinions only. Take them for what you feel they are worth.

you know better than that, this is the internet we will browbeat you to death, with the same stuff I heard from my bus driver's best friend over and over again until you give up or get banned. If that doesn't work than than you must be ghey or somethingOh come on you guys are ignoring my common sense/rational/positive comments thats just not fair...
