What other new issues have arisen? Your last post said just one. Try Lancers or USGI and your problem likely goes away. I haven't tried Lancers. They may or may not spit rounds. But I assume they will still get pushed into the rifle and get hit by the carrier when shooting prone. Frankly, I don't want to have to buy dedicated mags specifically to run my ACR. Unless I'm running 6.8 or 5.45 or something. The ACR is supposed to be a modern 5.56 rifle and, as such, should run correctly with just about any AR mag I stick in it. Also, the SCAR suffers from the same lack of internal mag supports. The SCAR will spit rounds too. But in the SCAR's defense those guns were likely spec'ed out using FN steel mags not USGI aluminum. What about the XCR? Never messed with one of those.... |

Also to people calling out modularity, how many stocks are there for the SCAR? How many caliber conversions? Different barrel lengths? What about factory handguards?
The MCX is the only one right out of the gate that has lived up to it's modular potential. Bushmaster is behind them, but there's not even anyone in 3rd place. My next buy will be an MCX, but I much prefer the controls of the ACR versus another replica of the AR15 layout. |

My next buy will be an MCX, but I much prefer the controls of the ACR versus another replica of the AR15 layout. The MCX is interesting in that it is basically a new rifle that's been built to fit onto an existing M16 lower. Anyone with a full-auto or SBR registered lower can upgrade to an MCX with the purchase of an upper and the stock adapter plug. This leaves the Robinson XCR. Looking at the website, they offer a variety of parts and barrels. But I've yet to mess with one of these. The only thing I've ever seen mentioned bad about the XCR was a cracked gas block and that was a number of years ago. |

Yeah, Sig came out swinging compared to Bushmaster. I think Robarm is the only one that followed through on x39 conversions, but they change the entire design of the rifle so often I couldn't consider it.

I still think the top contender will be the HK433. It will be the first gun that uses an adaptable gas system, and the first single receiver for 5.56 and 308. Swap out the barrel, bolt, and lower, then twist a knob and you can go from 5.56x45 to 7.62x51. The SCAR was originally supposed to be this way. Colt kind of did it, but I wouldn't call it the same since it's only the lower.
I have no idea how, but they're apparently using the same gas system and springs for 5.56 and 308. It looks like they're doing some major venting near the OP rod, so maybe they have a truly self regulating piston, not the common "kinda self regulating". Add that it's going to be cheaper than the G36, which post sample G36's were going for the same price as SL8's when both were available, around $1700-$2000. |

I bought my ACR a few weeks back and mine had the lighter barrel. No M4 cuts. 1/7 cold hammer forged.
Ambidextrous charging handle Upgraded safety with metal tumbler. They just released a new M lock handguard and I think the rifles newer than mine will have all the above features as well as the new handguard. The combination of the lighter barrel and the new handguard is a huge improvement in weight. Also fit and finish is good. |

As a general fyi, sig wasn’t allowing dealers/sots to even purchase the sear trip required for an auto mcx setup. I tried to get one for a post sample setup for work and they wouldn’t allow it whatsoever. Not that it’s a major deal but since auto mcx’s were brought up.

Quote HistoryOriginally Posted By TURRICAN:
Have they made any comments if HK will sell that rifle to us mortals? Germany does what the US was trying with the M4IC. Where if the military adopts the rifle, Germany owns proprietorship over it per the contract. So if HK wins the G36 replacement trials, Germany would control who it's sold and exported to. It's most likely Germany would continue legacy trends and only allow HK to sell it to military and police allies. This is why we get all current HK production rifles except the G36. We could likely get a muddied up version like the SL8, as that was approved by Germany as not breaching the G36 contract. It also means we could end up with a true G36 if HK gets awarded 433 production on a contract. HK on the other hand is selling almost every part you need to convert an SL8, in full knowledge of why people are buying them. Of interesting note, if Remington had won the M4IC with the ACR, they would have sold the entire rights and production to the military, and we would no longer have civilian ACR's or ACR parts. Bushmaster, Remington, and Magpul would not have manufactured anything for it anymore, which was when most companies bailed out. |

I have two, mags fit tight, but drop free, very little slop. That said the xcr uses a completely different feed angle, not requiring the need for m4 feed ramps. It feeds perfectly straight across the top of the mag.
I had two acrs and sold both, I replaced them with at first one xcr, I liked the first one so much, I bought a pistol config.  Attached File |

It's very well known that Travis Haley had a falling out with Magpul when he left, so he goes out of his way to talk shit about Magpul products, including the ACR, even directly contradicting things he said when he was enthusiastically promoting Magpul stuff (a lot of which he designed and holds the patents for). Nothing he says on the subject should be believed. Having said that, nothing that Travis said about the ACR is a lie. I had a 2018 era FDE gun that was a shit show. Receiver screws fell out. Brand new M2 and M3 pmags would vomit rounds upon rough inserted reloads. Firing prone would result in the bolt slamming into the inserted mag since there was no over insertion stop. My QD barrel wanted to QD itself as the barrel would NOT stayed secured. The ratchet system in mine was defective and would back off resulting in accuracy loss and a potential headspace issue as the barrel started to move forward in its trunion. I liked the rifle to a degree but anyone thinking that this thing is a refined product is out of their mind. The platform just requires way too much work and money in order for it to start being a "good" rifle. I really wish this wasn't the case as the platform concept is super neat and I have such a crush on it from years ago when it was the Masada. I wont shit on anyones parade if their like their rifle but I think we all need to be realistic and accept the fact that the gun is flawed as can be and needs attention in order to become half of what it should be. |

Quote HistoryOriginally Posted By Melvin_Johnson: The over-insertion stop is too low to work on my ACR. I can still pop a mag too far into the gun. Which modern non-AR rifles that use M16 mags have unsupported feed lips other than the SCAR and ACR? I guess I'm just kind of amazed that when Pmags break dozens of SCAR's people blame Pmags, but 1 in 3,479 ACR owners seat magazines hard enough to pop a round out and it makes the ACR a crap rifle. I'll just run Lancers like I always do and not have to worry about my rifle liking them or not. I do wonder if the ACR mag release could be modified to fix this though. |

Well, most ACR owners have no issue. That said, I’d suggest users be sure to depress the plunger before turning. Same kind of thing with AAC 51T mounts.

I just got mine from a huge gun dealer in KY. Its a Huntsville ACR with a non M4 barrel that looks nitrided. Aluminum is anodized, I got the standard model with polymer / heat shield fore end. It is tight as a tick no play between upper and lower. Barrel is marked marked BFI 5.56 NATO 1/7 The flash hider is a 3 prong with external thread and ratcheting cuts for a suppressor. I put magpul sights (buis) on it and a magpul qd sling. Can't wait to fire it looks like a winner to me. Also to note it has the ambi charging handle.
