ACR Media and Info Thread

I'm sure this has been discussed but if I bring my non restricted acr to the range am I allowed to put on my 10.5 barrel and shoot and then put non restricted barrel back on and go home ?

No, definitely not.
As soon as you put the short barrel on you are in possession of a non registered restricted firearm.

If you want to shoot it with a 10.5 inch barrel you have to register it as a restricted before you can shoot it and when you want to switch back so you can shoot it away from the range you have to wait till they actually finish removing it from the restricted registry (a one to three month wait) before you can legally shoot it.
The 30 day grace period does not cover taking it out and shooting it. The 30 day period is for you to be able to take it to a firearms verifier to do the paperwork, not to give you a grace period to play with it then switch back before the 30 days.

I spoke with the CFO lab when I got my ACR because I wanted to do the same and that was the answer I was given.

Is there a Canadian dealer that specializes in ACR mods. Like lightening the bolt or different trunion?

Why would you want a lighter bolt? What benefit do you expect to see with one?
Without an adjustable gas block or different action spring all you'd do is make it less reliable.

I've seen alot of the lighter carriers and other mods on ACR groups and they say it helps the felt recoil, make the rifle lighter etc.

But I could be completely wrong.

That works on AR's with adjustable gas blocks and different springs to compensate for the change in reciprocating mass. I doubt you could take away enough material to feel a difference in weight though, especially if you hang a bunch of stuff off the forend.
 
That's an interesting test you did, I think you're simply experiencing what a little heavier rifle does. The more it weighs the less recoil you feel and the less the gun moves with each shot. The ACR is a very smooth shooting rifle, but you pay for it in weight.

Be careful shooting steel that close, I've had bullets come back before, hopefully your steel is angled properly so that doesn't happen.

We thought it wasn't so much the weight of the rifles but more likely something to do with the weight of the bolt or possibly just a subtle differences between the way the gas systems cycled.

Whatever it was, the ACR was waaaay better in rapid fire mode.

BTW... Luv the tan colored ACR pictured above... I wish mine was FDE.

See my comments on rapid fire above before modding the bolt.

As for the trunnion... That's on my gotta do list.

I don't understand the "gotta do" when it will only drop a few grams off the rifle then see guys hang lights and lasers off their rifle adding way more weight to the muzzle.
Same as the guys who spend hundreds of dollars with light weight parts for their sleds then you see they are 100 pounds overweight.

My ACR with my NR 300BLK conversion :)

We recently did a side by side speed test with 10 round mags between an ACR DMR and a Robinson Arms XCR 3 gun model.

Basically we stood about 15 yards from a steel plate about the size of a mans upper body and tried to hold on target while pulling the trigger as fast as we could.

The difference between them was astounding.

Every shot from the ACR easily hit the steel target whereas less than half the rounds from the XCR hit steel.

We repeated the test with and without a tight sling and the results were always the same.

Slow fire accuracy at 100 yards was similar with a slight edge to the ACR DMR.

But shooting fast, the ACR is far more controllable.

I would like to try this test again some time comparing the ACR to an AR.

Same muzzle device on both guns? Same guy, with the same stance, using both guns? All of that can make a difference....

Definitely not a scientific test where all variables were considered but it sounds fun. Their results are exactly what I would have expected based solely on the weight of each rifle.

15 yards on a torso sized target and hitting less than half from the XCR tells me they are not well trained in how to hold and control a rifle but as long as the same guy shoots each gun that variable is at least consistent for both rifles tested.
Muzzle devices being an unknown could be what made such a big difference in how they were able to handle each rifle.
What optics did each have? Aimpoint on one and a 3-9 on the other could also make a huge difference in how easy they were to shoot fast on a close target.

Too many variables not accounted for to really take anything away from it but I'm sure they had fun :)
 
Sadly I gave up on my 10.5" ACR build. Such a great platform that's bones by our stupid gun laws (and super expensive multicaliber exchange kita/builds).
$1400 for a 7.62x39 barrel and bolt.

For a DMR build, what do I need to attach a handguars to the polymer handguard?

I'm assuming you meant rail to the handguard?
Magpul MOE rail sections will go on if you can still find any now that keymod and mlok have taken over.
In my opinion, skip the rails and the lights and the lasers and whatever other useless crap makes it look tacticool. Rifles don't need any of that unless you're shooting at night or trying to look cool.
Buy a quality optic and shoot it.
They're already a heavy rifle, the last thing they need is crap hanging off of them that serves no real purpose.

If you want another caliber have a 300 Blackout barrel made, then you only need the barrel and gas system.
I had my NR 300BLK barrel custom made and it works great, with my handloads I'm hovering around 1 moa (slightly better some days) and it's 100% reliable.

X39 is a chit cartridge for any rifle designed for 5.56, most have issues feeding reliably from mags that hold more than 5 due to the heavily tapered cartridge in a magazine designed for a cartridge with almost no taper.

Yea I need a rail put on the handguard so I can attach a bipod. Not sure if I should do old faithful Haris bipod or try a Magpul one. So look for magpul Moe rail sections.
For an optic I'm floating between elcan spectre and acog 4x. Toying with the idea of a 1-8x strike eagle but it feels like heresy putting a $600 scope on when better quality ones are collecting dust.

I have a budget friendly Specter DR on the EE if you don't mind some scratches to save $1000
