ACR Media and Info Thread

Got to the range this weekend, ACR runs fine, the hand guard didn't fall off as I expected it might, appears to be as tight as it was before going to the range, the 22 shell casings didn't shift or slip off, so it seems to hold for shooting at the line/off a bench. The hand guard also did not get hot, or even noticeably warm.

Will have to take it to the lower ranges one of these days and abuse the thing a little more to see if it will work out under less pleasant conditions.
 
Mister donut, if you want to reduce the wobble, "crush" the handguard abit in a wood lined bench vise. Just a little bit so it makes a tight fit against the upper rail of the ACR.

I did that with my WE rail and it will support the weight of the entire rifle with no pin.

Also, I think the best barrel ever made was the stainless steel Questar branded barrels 1:8 with Wylde chamber. Incredibly flat shooting.

Cool! Glad to know I'm not the only one running this handguard! How long have you been using it? How's it hold up over time?

The wobble actually isn't actually an issue with the width of the handguard. The handguard is actually a pretty tight fit that way. The loose bit has to do with the retaining pins on the WE unit versus the retaining slab on the real deal:

Not exactly the best angle, but you can see the one on the left (real) is a square slab compared to the round pin on the WE unit on the right.

On the receiver of the real deal (pictured below, top rifle), the height of the slot opening is too large for the retaining pin of the WE unit (below, lower rifle), thus the wobble (up and down, thought very slight):

I found the M5 screws but haven't located the M5 threaded 10mm long brass stand-offs. The brass caps I made from 22lr casings I cut in half seemed to work, but would be nice to find a way to secure them better to the factory WE screws. I might try to see how the fully threaded M5 screws will fit into the .22LR shell casing, who knows, maybe I can even thread the inside of the shell casings? Will give it a try after work today.

After playing with a couple NR ACR's with the Questar barrel I made some trades and now have one in my rifle. I haven't had a chance to do a lot of bench shooting with it since the trade but it does pretty good with cheap AE black box 55gr out at my buddy's farm :)
I'm looking forward to having some time to shoot it off a proper rest with some various handloads to see what it likes.

I've had it for a few months and done bench, prone, barricade shooting, banged it into nearly everything. Haven't shot 3 gun with it, but I feel confident it will hold up. It was originally tan and I spray bombed it black so it really has alot of character now.

I think it's pretty tough overall and should stand up the the rigors of my weekend warrior range visits.

After crushing the handguard abit, I haven't felt the need to "fill in the gap" yet because it grips the upper rail quite tight.

I should probably get on that sooner than later however...

It's been speculated that these Questar barrels are white oak barrel, rock creek, or mike rock.

To date, I've been trying to burn up my AE 55 gr (a rather fun prospect I might add) at 50, I can hit the small steel (which looks to be about 4"x4" at genessee) offhand, on paper I got some really good groups, a shame I didn't have a phone with me so without proof, I won't commit to anything :)

With the same 50m zero (and yes, it is exactly 50m from the firing line when I ranged it, good job CHAS/Genessee) I can goto the 100m range and ring the 4"x4" steel plate offhand until my arms give out.

Sitting on the bench, it will hit the steel with with every shot.

Despite it being so front heavy, I love the consistency. Guess I'd better work out more!.
 
Well just got a B-GRF Geissele Rapid Fire Trigger and a BCM MOD3 vert grip from Brownells today, Hopefully it will get here before the ACR... lol...

Good to know, pics of your rifle please!

And definitely pics of your when you get it!
 
Vid from this past weekend:


That AAC three prong flash hider is surprisingly effective as a flash hider, holy. Compared to another rifle I was testing out that weekend:

Not the best pic, but it's what I have. They both wear a lantac Dragoon muzzle break and one is wearing a WE MSK handguard.

Two big improvements that can be made are the enlarged bolt release and the 45* safety.

HUGE improvements for less than $20 each.

You have a WE MSK handguard on one of them? I can barely tell the two apart....actually, I don't know which is which, haha!

OK, this is a dumb question, the lower receiver is generally the "firearm" according to our laws......but the serial number is stamped in the uppers on our ACRs......?

no, you are comparing it with an AR which the lower is the "firearm"

swiss arms, SL8, most other firearm designs have the "upper" as the serialized part

So, the complete unit, upper and lower is considered the firearm when it comes to ACRs? I know in ARs, just the lower is registered, and is considered the firearm. Same goes for pistols - just the frame, but I was looking at my ACR lower today, and there were no markings whatsoever. Could I theoretically find an owner of a tan ACR, and swap my black one with him? Not that I was going to do it, but was just wondering.

There was also talk about custom billet alluminum lowers possibly in the works, so would that be considered a firearm, or just a lower, a part of a firearm when it comes to ACRs?
 
No, just the upper is "the firearm"

I believe this was done as the ACR beings an "Adaptive Combat Rifle" was planned to have to have different lowers to acomadate AK mags as well as AR10 mags for .308.
where did you read that?

The original release of the ACR spoke of caliber conversions in varying calibers but I saw no mention of any mag well changes or a 308 offering in the small frame of the ACR. Remington 30 AR was stated as a conversion that would be available in future but it uses the same 223 magwell while delivering close to 308 performance

I've never heard anything about a 308 version. You would need a new upper and lower for that. Basically a new everything.
5.56, 6.8SPC, 300BLK, and 7.62x39 are the only conversions I've ever heard of as factory options. None of those ever made it to Canada though and other than prototypes I don't think any AK magazine lowers were ever produced.

There is a video somewhere on youtube where they had a AK magazine compatible lower but that was back when it was the Magpul Masada. Since Bushmaster/Remington took it over I haven't heard anything further.
