Wondering if anyone had any experience with these new models?
I have the original 901-16S (that came with the complete kit for swapping uppers). Love it and have had zero issues swapping the uppers back and forth. It's a keeper. Great shooter and not "ammo picky" for functioning. BUT, as we all know crappy (cheap) ammo=crappy groups. Better ammo, better groups.
I opted for the new Colt Competition "PRO" CRL-20 and have it ordered from SHOT Show. "Should" be here late March/early April.

What kind of accuracy were you getting with your 901? I'm looking at the AR901-16S as a budget (without a build) means of getting a 308 gas gun.

With good ammo or reloads I'll holding onto 5/8s groups at 100 yards.

Thanks for the info guys
I've been looking at this system for a while now ever since I took a second look at it and noticed that they went with a smaller BCG, smaller, shorter lower receiver, and balanced the carbine out very well. This is basically picking up from where they left off with the Colt AR10A from 1959, which was a much different gun than the Hollywood ArmaLite's from Stoner's proptotype & RDT&E guns.
Biggest con right now for a lot of people is that you need to attend the Colt specific armorer's course for it, in order to get the unique barrel nut wrench for it, but I think this carbine is a sleeper in many ways.

What length is the gas tube?

My friend picked one up at a gun show. I almost wish I had gotten that model over the one I bought with the monolithic upper. It's significanlty lighter, although it does dispense with the ambidex controls.
The model I picked up came with the conversion kit. I haven't fired it much but it's been 100% reliable with American Eagle .308 150gr FMJ, and Federal XM80 149 gr. I don't have an optic on it - yet. With open sights, I can break clay pigeons at 100 yards. I swapped out the IMOD that came with it for an extra EMOD. I like the EMOD much better for this gun. I swapped out the stock Colt grip for a MIAD. The only issue I've experienced is that grips with high tangs won't fit without modification. I ruined the two back straps that came with the pictured MIAD trying to get them to fit. I have an extra Tango Down BG-17 laying around that should be much easier to modify to make fit. I want a fatter grip, though the MIAD with the slim back strak still feels pretty good.

I came to the same conclusion, I think value wise its the best option for getting a gun that uses .308 PMAGs, with a free float upper, and has a quality name to back it up.

I've been playing around with a 901SE and I find that I love how it handled compared to the 901S. However when shooting it that pound shaved off it makes a noticeable difference.
anyone know what pattern the upper receiver is based off of on the AR901-16S for rail replacement? AR10, DPMS HI/LOW, ETC?

The 901 series is all proprietary, and only use 901 uppers. The rails are all monolithic except on the 16SE, but the rail on that is unique and cannot be swapped.
Been researching 901s. Found mixed reviews, re shooting and parts availibility or lack thereof. Verified posters claims of a number of 901s available for re-sale online.
I have both models, the LE-901 and the new MARC 901. Both shoot nice, probably due to the vortex hider up front. The MARC is better of the two in my opinion as it doesn't have the big quad rail like the LE901. The issue I have with the 901 series, is the dog ear on the right side of the lower trigger guard. It is a lot thinner than any AR, and I broke mine on the LE901 from side impact. Colt wanted $900 to reissue a new lower and I opted for a spare MAID with integrated trigger guard. No issues with PMAGs, C Products, or the KAC mags. Both shot reasonably well with 140-ish grain ammo. Not too heavy, but not a boat anchor either. Both of mine sit in the safe now, as I'm gonna lug a MR762 around for year and see how that drives. It is already noticeably heavier, but, meh.
I can see why they are out for resale. I inquired with Specialized Armament about cutting one barrel down, but SA does not have the tools to remove the barrel from the monolithic upper on the 901. I also asked my dealer to order one of the factory short barrels listed in the manual, again no dice - not available as of yet

Could you post a picture of the breakage?
The only thing I don't like is that they only come with heavy barrels. That unfortunately is a deal breaker.
Anyone else with feedback on the AR901-16S? It seems to be a great beater 308 rifle, and should be much lighter than my OBR.
I have that rifle. I had a 16" PredatAR a few years ago, and even though the Colt is listed as being a heavier rifle, it feels much lighter. I put a SWFA 1-6 and a Giesseille SSA-E in it and it's now my favorite rifle. Much more reliable than the Larue I owned.
One mistake I made with the PredatAR was not having a defined role for the gun, so I ended up shoe horning it into roles it wasn't optimal for, and so I stayed frustrated. Before I got this one I decided it would just be a much more accurate, lightweight, and modular FAL, and this has helped me enjoy the rifle much more.
Excellent to hear. I am with you on your thinking. I just want a modern FAL/308 thumper, and I dont want to spend 3-5k.

I have an Ar901 and I dig it a lot. There are some differences to deal with in getting one.
The rail sits slightly higher than standard. I found a CTR and Larue RISR made the ideal cheek weld. However the stock must be in the 2nd position out of the 4 for the charging handle to pull back. No biggie, just something to be aware of. Consequently the charging handle is a different length and I don't believe there are aftermarket ones.
The grip is different, so you need a specific grip for the 901 or 308. You can also just file/trim the blackstrap-easily done. I don't believe the trigger guard is replaceable but it is wider and doesn't dig in like a normal AR. The grip wedge that slips between the grip and trigger guard works well here and it's cheap.
The newer models don't come with the adapter. The AR901 doesn't have the ambidextrous controls either. But at several hundred dollars less, I'm not complaining. I got this rifle for long range hunting and it fit the bill just right. It has been one of the most accurate semiauto rifles I have.
Right now I suspect it is over gassed with a suppressor. The buffer is already maxed out with a 2.5" buffet and 2 tungsten weights. The AR901 does have a low profile gas block and I think I could put an adjustable one in there vs the Le901.
I think the problem grips are the ones with a high back piece, I put a BCM Mod0 on mine with no drama. I also put a BCM trigger guard on mine but it did require a little bit of filing.

What length is the gas tube?
Without taking the tube off and measuring it, it looks to be just a little short of 12"
