Now that SBR laws have relaxed in most of the US I think you’ll probably see more ACR being shortened to the size I think they excel in. Shown is my shop test gun with a converted 12.5M Sionics ER barrel. These have been my favorite to convert and gas tune for customers and they shoot great.

Anybody have or know where to find a blow up parts diagram for the Bushmaster ACR? I can only find the manual of operations pamphlet.

Swapped a customer’s original 1/9 barrel and converted a Bushmaster 1/7 barrel. Cut to be able to be pinned with SF3P (ends up being a ~13.9” barrel prior to pinning), relocated all the original ACR components, gastuned down to work nominally, reproduced the M4 barrel and gasblock slightly for weight, and re-parkerized. Of all the barrels to pay to have converted I’m not sure why another Bushmaster barrel, but I do what I’m told.

The Coyote Brown is the most iconic in my mind, but the black sure draws the eye as well. What’s your favorite? Side note, the ACOG looks like it belongs.

I don’t have the highest hopes for these and I’m going to have to machine interface parts to attach it properly to both the receiver and front trunnion, but I quite like the look of the chubby, shovel nosed Gen 1 RemDef handguards and its at least cheap and made of aluminum. If it doesn’t work out I’ll just do the polymer, 1913 tri-rail, or AAC Square Drop ones I have.

Anybody rocking one of these? Looking at adding one to the stable and wondering what others have done in terms of barrel options. It seemed Bushmaster offered a 10.5", 14.5", 16.5", and possibly an 18.5" variant? I understand standard AR15 barrels can be converted with some work depending. Bolt will be needed so the hunt for parts will be a patient one.

Photoshopped 12.5" carbine for reference (not my original photo).

I was able to get a fair amount of barrel parts from midwest gun works so I didn't have to strip my stock barrel completely. The only thing I couldn't find and had to re use was the piston/spring, regulator, and piston guide block. I also didn't want to drill for taper pins so I experimented with set screws and dimpling the barrel. I need shorter screws but the proof of concept is there. The gas block I got from MWG was also silver when it arrived so I used a high temp spray paint so we'll see how that holds up

Haven't fired it yet but the headspace is good and the gas port is .02 smaller than the standard 16" so I should be able to open it up and get it tuned

Wondering if buying a DD barrel to get chopped then sent to templar is worth it pending the wait times for it. Or just find another acr barrel to get chopped?

Has anyone here gotten barrels from Templar Precision lately and if so how long did it take to arrive post order?

Thanks

Looking for a place to talk ACRs. Glad to see folks love them as much as I do. I purchased her new she’s a factory 6.8 and I have a 14.5 5.56 that I shot. I tend to leave the 6.8 barrel in the safe. I was going cut down the 6.8 but got told not to do it. So I left it alone.

Take care

Local FFL has this on consignment and man she's hot! Comes with an additional handguard and 2 barrels!

TA33 fits nice on the ACR SBR…

I'm trying to use the parts of a spare take off 16" barrel to put on a 12.5 midlength barrel and noticed the gas port on the 16" is much smaller than a 12.5 carbine barrel I had lying around. Has anyone ever fitted a barrel themselves and what gas port size or factory barrel did you use to get reliable cycling both suppressed and non suppressed. I'm trying to figure out what size gas ports are on 12.5 midlengths from a couple suppliers but it seems like sionics is the only one that has reduced gas port options.

I’m having issues running my 10.5” ACR suppressed, even when using the suppressed setting on the gas regulator. I’m getting FTEs and double feeds non stop with this thing and I’m not sure why. I’m running a KAC QDSS NT4 suppressor, if that matters. Any insights would be greatly appreciated, thanks!

I have a 16 inch barrel that i’d like chopped to either 14.5 or 13.9 and then have the muzzle device pin and welded. Who do y’all recommend me to send it to? I tried looking on templar’s website but idk it doesnt seem they offer that service.

I’ve always wanted one , 1 small thing it had a lose safety selector you can push it a small amount to each side ( side to side) just feels a little lose. This an allen key and what size or is a worn a safety selector/ part in side ?

I know I'm the millionth person to make this post after making this discovery but I too have found out the hard way that the polymer handguard requires a different pin than the mlok one. Is there any reliable source of the pins right now?

Thanks.

Happy Memorial Day!

On my birthday this year my friend agreed to sell me this guy, got a really good deal on one of my favorite rifles so I was really stoked on it. took it to the range once. setup exactly as he had it, didn’t get the chance to do much other than the temporary pressure switch kyber pass tape but really just needed a zip tie. Figured enough time has passed that it may be divine intervention that I ever get this back. I know how it was layed out was dumb, that will change.

I can't believe it! Still doesn't feel real. Was at the end of my work day and happened to stop at a LGS before heading home. It ended up costing me $2500 but well worth it. I finally own a Bushmaster ACR! It looks nearly new, very low round count. It came with the Bushmaster hard case, two mags and the manual. I am absolutely stoked. Its nostalgic for me as i was playing MW2 back in 2009.

I was trying to switch the gas regulator on my ACR to suppressed mode the other weekend, was able to turn it about halfway and it got stuck. There seems to be some rust/carbon buildup in the plug somehow (I’ve never run it suppressed or in wet conditions). Any ideas on how I can get this thing unstuck?

Hey guys, I figured I'd show you my progress on the lower. I've been crazy busy the last few weeks, but I finally got around to putting it together. It came out fantastic and looks exactly like the oem finish! I'm very proud of how well it looks!

Hello everyone, I took the buffer (if that’s what it’s called) out of the left stock as it was in 100 pieces all over the lower. Are these available anywhere or is there a remedy for this? Thanks for any help!
