The SBR M5 has turned out to be amazing. Socom profile barrel, H2 buffer.   Good deal

I can’t quite tell but the forge flashing might look a little better than some previously posted rifles?

Is it just some of the photos or is the upper receiver purple?

I may have missed it earlier in this thread, but do these just use 6940 barrels?

Also, what gas length and barrel profile is on the 16" guns?

Do you know if Colt will be offering just uppers? Specifically looking for the 11.5" and 14.5" uppers. Thanks!

Carbine length

Hopefully colt will offer these in upper form.  The 16 inch M5 is carbine length.  I shot the M5 SBR suppressed and unsuppressed today (LaRue Tranquilo) .  The gas port is .74. I put a new gas tube on it that is .67. The barrel is socom profile..  I shot Mk318 Mod 1.  30 rounds.  No issues. I put a LaRue MBT trigger in the gun as well.   I noticed no impact change at 50 yards. It also has a nice Holosun green dot.  I will get a photo posted soon.

Thanks Master Guns, the SOCOM profile definitely makes these more appealing. Since Colt builds their rifles with correct gas port sizing and buffer weights for the barrel length and gas system length, the carbine gas isn't a turn off for me.

MGSgt. I do like your M5 SBR, but why change to a smaller gas tube? Wouldn't it run suppressed with issued gas system? I realize & depending on the suppressor 'back pressure/ blow back.

I ask because my initial impression was that the original design Colt M5, doesn't it have an adjustable gas block? Are we being short changed?

My Colt 11.5 barrel runs supressed fine ejects 2-3:30 by itself. Though, I ha
ve another Colt 11.5  I've tuned with an Bootleg adjustable bcg and is very smooth like running a sewing machine & it ejects 3-4 o'clock.

Did Colt change its design for the commercial market (no adjustable gas)?

Eta: I could be mistaken and am thinking of the CM7 with adjustable gas.

One of my friends does a lot of tweaking. I am shooting it suppressed. .67 give me a little nicer impulse.  Not needed at all.  Just something I wanted to do.  I have a 6933-EPR and it has .74 and it rocks. I also have a 6933 FBI profile with a .70.  It's full auto and it's great as well.  No reason to switch. Again, just something I did.   I've never seen a colt factory with adjustable gas block.

the 16 inch M5 is government profile with H buffer.

the M5 is a very slick design.  Once I took apart the SBR and checked it out and how the barrel and rail attach I was impressed. Much better set up then EPR.

Is this confirmed?  I do see this from Colt.

I also see Charlie’s (I know, I know ) has the same listed.  I suppose they would do the same thing though.

Finally got around to ordering one of these M5s from AU, should be at FFL Thursday, hopefully they have it ready by Saturday to pick up.

Been off the Colt kick the past 3 months, been going to flight school then bought me a used Cessna lol.

I got to inspect my 11.5” M5 at the FFL/SOT and noticed they changed the starboard side bolt release lever.  The 10.3” should get here next week, but I think it will have the same revised lever.  Never even looked at the pictures on AUs website before I ordered.

I wonder why the changed the right side bolt release??
8/10/2023 7:50:27 PM EDT

LOL - no idea.  I guess in 9ish months I can play around with it while shooting and see if it makes a difference.  It definitely sticks out a little more from the receiver than the type on the 16” M5.  I don’t think there was any less or more of a gap between the lever and the receiver side - if that makes sense.

I picked up my M5 this morning along with the Euro Colt. Really stoked, the M5 looks amazing. Not sure which version bolt release I got, have to review that and take a look later. Only a quick inspection at the LGS.

I believe soldier systems stated that variant two allows for the bolt to be locked back from the right side as well.  Developed as part of a contract requirement.

I did exactly that.  A guy from customer service wasn't very cool.  He even told me that I should by a new if I want the current lever.  I asked to talk to someone else and he flat out refused to let me talk to someone else.  1st time I have ever had bad customer service with Colt

All of my Colt carbines have 6 position Colt tubes on them but those were installed by Specialized Armament not Colt. I don't really use the extra positions so it's more of a cool thing to have than anything else.
