the big thing I herd about the SCAR was that anything that they attached to the bottom rail was being directly affected by the heat of firing the rifle because it was to close or touching the barrel…
any accessories were almost melting.

Having a couple of hundred rounds thru my ACR now, I’m satisfied with my chioce over the SCAR. I like a little heath plus great looks
(basis model) and accurate…3/4" at 100. Maybe not be for everyone, but works for me. Bullets and beans for the future.
Thanks for the feedback on the review. The recoil is interesting, as I thought the heavier rifle would handle it better. I would love to shoot both rifles with a suppressor!
I also agree that there is a subjective factor, too - possibly based upon shooting experience. You folks out there who really know how to properly hold the rifle may experience very little perceived recoil difference between different platforms.
It would seem that design could also be a partial factor as brought up in a previous post. How far off of bore axis is the recoil impulse? How effective is the recoil buffer system? How much mass is moving on recoil? How much of a difference does a muzzle brake contribute? I would imagine that all of these can make a difference - perhaps it is the balance of these (and other) design factors combined.
What is the actual weight difference between SCAR and ACR?
ACR has a Government profile barrel, which would account for some of the difference. That would also make it more front-heavy.
My SCAR weighs exactly 7.5 lbs bare (without optic, sling etc.) with following weight distribution: upper 4 lbs, BCG 1 lbs 6 oz, lower with stock 2 lbs 2 oz.
Comparing to similarly weighted AR (3 lbs 13 oz upper - 11.4 oz bcg - 2 lbs 10 oz lower/stock) , the front balance of SCAR is evident. Also evident is double the moving mass of bcg, as I had mentioned earlier.
Maybe our ACR owners can measure theirs for comparison.
ACR has been confirmed to weigh 8.2lbs which is the listed weight. Its front heavy due to most of the metal being in front of the magwell. SCAR has a lightweight profile on the barrel as well. ACR lightweight barrel in 1:7 would be nice.
IMO the heavier acr was easier to run because of the weight, in compa
rison to the scar. My acr now has a PWS break and its very nice. Recoil is less than the scar.
With that being said the only thing wrong with the scar is the manufacture .
Has anyone carried the ACR for about 8hrs straight in 1 day? I am thinking about buying one for tactical carbine courses but would like to know how it feels or how tired one will get towards mid-day or end of the day.
Care to elaborate?
Fn isn’t releasing parts for them , quote from them “never”. Everything breaks and when it does you will have to send it back to the factory .I was at a eag tactical class and yep one broke and had to be sidelined because their are not parts for them. Sure would be nice if you could get an extra BCG hint,hint.
That’s whey I bought an ACR and just shoot my bros scar every now and then. 8 do like them
I have several times on a OSOE one point sling. Not a problem.
The ACR is a brick compared to the SCAR.
It might be okay for the bench or gaming, but a combat weapon, which the SCAR is, weighing nearly 9lbs naked is a no go.
M68 + loaded mag + PEQ16 + light and the the ACR would be unbearable.
However, you are right in saying FN is doing less than a bang up job of supporting the SCAR 16S
Id be intrested to see what it would weigh with a barrell profile like the scar’s
Agreed.
I am willing to wager it would clock in around 7.3 with a light barrel.
The XCR weights nearly the same as the ACR when it has a heavy barrel. I assume the weight savings would be nearly the same as well.
If I when I get an ACR, it’s getting SBR’ed ASAP, so I am not too concerned about weight. The ACR will probably be just under 7lbs with a 10.5" barrel I bet.
Bushmaster has taken some large missteps with the ACR launch, but they are just a few tweaks and corrections away from having a very appealing product that can be competitive.
I talked to a bushy smith today about just that, sbr and was told that the smith that tried to open the gas ports would curse me to high heaven. He said the barrel is so hard that it would break/dull quite a few bits before you got any where.
I was having this very conversation with the guys at Robinson a few months ago. Nitride treated barrels are tough as hell on tooling.
Good review but they should share the same muzzle device to get the best handle on the real differences in muzzle hop and recoil impulse. The PWS FSC-556 on the SCAR makes a huge difference. I shot a 556 SBR back to back with a SCAR and it seemed jumpy and a little heavier on recoil. I changed to the SCAR’s compensator and the SBR was softer and flatter shooting than the SCAR.
I own both the scar and acr. Both are awesome guns, too much trash talk about the acr going on, everyone needs to spend some time with it and they will all be believers. I shoot both guns side by side, they are both exciting and different. I think we are lucky to have the ability to own the next generation and future weapons.
I happen to like the acr more than the scar. I would not purchase another scar 16s, I would purchase another acr. In hind site I probably should have bought the 17s instead of the 16s but I needed to compare them for myself.
Check out the Tactical operator Magazine, current issue for a comparison, they chose the acr also. I also red that most socom guys are switching to the 17s as well.
I have to lean with ACR even with the weight penalty, the LW 1/7in barrels should make about 5 ounce difference when they make it out. The Remmy magnesium lower for the ACR (when and if they are available) will shave another ounce off. Ergonomics IMHO are superior on the ACR, mag changes are a good .5 to full second faster.
A buddy at work is running a SCAR 16s and I like it, just not as well. The stock on the 16s seems to flex when using an aggressive forward grip(achieved by extending the stock all the way out, sense the factory hand guard is carbine length), and occasionally depending on position the charging handle with graze my support arm, causing a malfunction (the new TD CH may fix this).
I had a Battle comp on my ACR for a while and I would say that it is at least on par with the scar 16s + pws break, probably a little bit softer recoiling. I moved the battle comp back to my goto AR, but plan on getting another for my ACR.
To the OP, when using the bolt release, place the center of your index finger tip on the button, and press straight down. You will have plenty of leverage to actuate the bolt release. If you press it at an angle it requires much more effort to actuate
Pics( as this thread lacks sufficient gun porn):
With cloaking turned on:
The bottom rail is attached to the barrel extension (near the chamber) only, and does not contact the rest of the barrel at all. It sits about 1/2 inch or more away from the barrel from the attachment point all the way to where the rail ends.
Heat is no more of a problem than a DD or any other rail on an M4/M16.
