Hi, does anyone have experience with the Spikes Tactical ST15 M4 LE Carbine rifle? It’s supposed to be a direct competitor to the Colt le6920, and I’d like to know how it stacks up against the “gold standard” of AR’s. Also, what’s the general consensus on Green Mountain barrels? Are they a hit or miss, or are they consistently good performers? I’m looking at the GM-M51 16" M4 barrel to have as a backup/spare barrel for my go-to carbine. For some time, I was thinking about building my own AR but recently decided to just go with a plain jane factory rifle like the 6920. I’ll change the handguard and trigger but that’s about it. Anyways, any input is greatly appreciated. Thanks a lot!
I vote 6720 over 6920. The lightweight barrel becomes much appreciated over time as it makes the carbine handier and easier to maneuver in my experience. Unless you own an M203 grenade launcher I see no reason for the M4 barrel profile. Claims that the pencil barrel is less accurate after heating up are greatly exaggerated. Sure, it looses a little, but almost every source I’ve checked it’s acceptable to me and probably most people.
If it was only between the two, I’d go Colt all day.
I’ve heard that before. :rolleyes:
I voted other. I’d go with the Centurion Arms CM4 complete rifle for $995. It comes complete sans BUIS.
I generally use GMB’s. Never been disappointed. They are an OEM supplier to other companies. I have the GM-M51 on one of my two A-2 fixed sight carbines, the other is a mid-length PSA stainless CHF upper. They both shoot about the same, good. I shoot the PSA upper more because it is a mid-length and I like the little bit of stretch out that the mid-length hand guards give me.
Not much help. but I wouldn’t hesitate to buy the GM-M51. I think that GM has had them listed for several years, I bought my on sale, you might want to check now and againg to see if you can catch a sale.
Green Mountain will make barrels to whatever specs their client wants. If the client wants an awesome barrel, they will pay for an awesome barrel. If they want a cheap barrel, they will pay for a cheap barrel. You as a consumer have to figure out how long the tooling is used, what materials are in play, and the level of quality that is paid for.
I voted other as I prefer to roll my own. This way, it is built to my specs and I do not need to change a thing.
just by a 6920
What kind of accuracy can I expect to see out of the GM-M51? (I.e. 1-2MOA, 3-4MOA, etc)
Today I’d go with the 6920.
My first rifle was a Spike’s with 16" M4LE barrel. I still have it (rebuilt as SBR with different barrel). I never had any issues with it. Not that I could consider what I did hard use. I did take beginner shooting class and then another full day class with it before rebuilding.
When I bought it 6920s were about 400 bucks more than what I paid. Now you can get a 6920 for under a grand. Why get something that’s said to be close to the standard when you can get THE standard for probably not much more?
If I were buying today I’d start with the 6920 or maybe the one that comes with the Centurion rail?
Good luck!

1 to 2 MOA - closer to 2 with the 55gr reloads I shoot playing around. I’ve never shot anything but 55gr reloads in that one.
I’m going to the range tomorrow, I’ll shoot some 62gr Hornady Black through it to see what it does with that ammo.
I put a colt 14.5” m4(punned&welded) in my 6920,I can shoot between 1.5-3” groups from rest pretty regularly.the geissele ssa was a big improvement also.
Another vote here for a lighter profile barrel.
Here is a target with two five round groups on it. I was too lazy to set up my spotting scope so I walked out to look and when I came back shot the second a little lower. I called the flyer in the first group (top) but IDKWTFH with the second group being lower. I took off a Burris AR332 off another rifle to shoot the groups, it was pretty much on for windage and close for elevation:
Ammo was some PMC 55gr I had in the safe, decided to save the 62gr Black. Shoots were at 50 yards.
After the ten rounds with the Burris, I took it off and zeroed the MATECH - which was a hoot since I didn’t have my cheater glasses.
Noveske will be the best for your build. The N4 barrels specifically.
Noveske hasn’t been the best of anything for many years.

Awesome shooting. Thanks for the pic!
lulz.
My very first AR-15 was a blue Label Spike’s Tactical ST-15LE. 16" middy included carry handle/sight. Shot it for a while with VG accuracy for me. Traded upper for a built upper and a stainless WOA barrel, 18" rifle gas system. I am still using the lower on a BCM upper. Colt lower on a BCM pistol upper. Wife’s AR is a Spike’s lower and BCM upper.
If I was buying a complete AR, it would be a Colt 6720, BCM, Sionic’s or Centurion Arms
6720 or 6920 with trigger, and MRO.
