I need a some guidance on the FH removal; I'm replacing it with a mount for either a Sico ASR FH for a Saker or a Griffin mount for a 30 SD. I've scanned the previous pages and didn't find an answer to removing the Vortex. Will putting the separated upper / barrel with vice blocks in a vice stabilize the upper enough so I don't over torque the barrel nut when removing the FH ? Do I need to use heat to loosen any thread locker ?I tried magpul BEV block but it wouldn't fit. Any suggestions appreciated. I hope this helps. |

IIRC it was a 22mm wrench to take the Vortex off. No threadlocker or anything on it. Hey, it's your gun, if you want to do things the wrong way and risk damaging it, go right ahead. |

I have an AR901 that came with a bird cage compensator. I used a Geissele AR10 reaction rod to remove it without any problems, its a little shallow but it fit. I did not see any locktite being used. I used an AR15 armorer's tool that had the correctly sized diameter wrench slot, luckily enough. The Geissele AR10 reaction rod is pricey but it will save you from damaging your upper receiver and/or your barrel indexing pin. I myself have taken the barrel off several times on two different AR901s, so for me it was an investment. I am currently running a SiCo ASR muzzle brake on my main 901, although I still dont have the suppressor yet. I hope this helps. |

I've got the LE901SE model and I'm liking it slick except that the forend gets pretty hot. Does anyone make some kind of cover for the bare portion of the fore end or am I going to have to attach all the rails and use standard rail covers?

Manta makes a sort of wrap around grip that only mounts to a top rail. You might want to try that.

I ended up modifying a KAC rail cover and bolted it directly onto the hand guard. I'll find out how much protection it provides tomorrow.

I predrilled holes through the rail covers and removed the two the rail channels on the back side of the rail cover. I found if you don't remove the rail channel on the back side of the rail cover, the rail cover won't lay flat on the rail. I'll try to post pictures later. |

Yep, that is exactly how I did it! Not sure how much it helped as I only did one on the bottom but I'm going to buy a full set so I can cover three sides and see how well it works.

Out of curiosity, has anyone tried an X-25 drum magazine in the 901? Did it work?
Manufacturer says it should work, but one Brownell's review says it doesn't. I kind of want to have one for shits and giggles. |

So far I've seen the slash heavy buffer and the jp captured spring could be heavy by swapping out a tungsten ring. I bought two of these in the past month and Jesus have I had a hard time getting the first one where I want it with all the proprietary parts. Picked up a Marc 901SE today.
My AR901 is ridiculously over gassed with a suppressor, so I've been looking at the jp captured spring as an option. |

Well, I ordered the 901-16SE M.A.R.C. from arms unlimited about two weeks ago after getting an in stock notice. As it turns out, what I picked up was a Mexican export marked lower with the older 4 rail 16s upper. I hadn't actually inspected the gun before posting, I just glanced at it when I picked it up, and thought it had the rail sections already installed. Box tag says LE 901-16SM.
I've emailed them to see what they actually meant to sell as the description never mentioned any of that and if I can't get the Marc model to get a return. My search for the Marc model may continue, or I might say eff it, and get a sig or dpms gen 2. The first one, AR901, I got off gun broker. |

Goddamnit, at least you got what you paid for. basically they said I can keep it or return it, no 901marc to replace it with. Mexican export lower has some dings, and upper is perfect, just not the Marc model I wanted.
deciding on sending it back next day or so, they said i lucked out with a "collectors piece" not sure I believe that, and I bought it to shoot. |

Consider it an investment, someone told me once that you just don’t lose with a colt. I have found that to be very true. Those 6920 colts with the Mexican markings were snapped up pretty quick and fetch a premium now due to the uniqueness of the item. |

Just dumped about $400 on spare parts on Brownells once I saw the 901 was dropped from the website. Sorry about everything going out of stock guys, I might have had something to do with that... Just wish there was a way to get a spare or replacement barrel once mine eventually wears out. |

Yeah, I am very particular, and I like my AR901 (except for the missing ambi controls!), but just couldn't handle the 16S upper. I just want a MARC. Arms Unlimited was cool about it, prepaid label etc. so no complaints there, but my search continues. I have an MBT trigger, a Razor and an Omega in jail and all the other parts waiting on the next 901 I try to buy.
Pro-tip (not sure if I mentioned this before): The gas key screw spacing is shorter on the 901, so no adjustable gas keys fit. Sad. I was hoping that'd be an easy fix for over-gassing. I've got a new adjustable gasblock to get installed on the gun below. Not sure what to do about the MARC though. Maybe convert the front sight block to DIY adjustable. Obligatory pic:

Odd, I read somewhere that colt was working on releasing an updated 901 sometime 2018 So I don’t really know what to believe. I tend to lean towards the reps I spoke with though. There’s really no reason to yank it off of the website unless they plan on killing the line. They keep it on the military side due to contracts they are trying to score |

Took mine out yesterday and shot it suppressed with a Saker. Experienced several double feeds and extraction failures. Its obviously overgassed. Anyone have any solutions for a heavier buffer and/or spring combo that can help solve the problem ?

I also shot mine with a Saker. Definitely overgassed. Had to put on an adjustable gas block. I used a micro MOA govnah.
Prior setup was stock buffer and spnico orange spring. Overgassed, uncomfortable to shoot. Ended up with Micro MOA govnah. suppressed port size around 0.055. Where the factory port size is 0.072. Stock buffer, changed spring to tubbs flatwire. Works great now. If you change the gas block, you will need an armalight carbine gas tube. The stock colt gas tube only works with colt FSB. Unsure of what the Colt low profile gas block and tubes look like. |

I just replaced the stock low profile on my AR910 with a superlative arms low profile, no need to change gas tubes. |

Thanks for the responses and suggestions. Followup questions: Is there a guide on removing the handguards given the monolithic upper and barrel nut setup ? Its been awhile but I recall reading something about needing a custom tool to hold and remove the barrel nut, or send it off to Adco or a similar service to get the hard work done.
ETA: Just found the reference to Arrington Accuracy Works back on page 42 about the custom 901 barrel nut wrench, but after googling him it appears his website is no longer operational. |

IWC71, what kind of 901 rail do you have?
My 901 is the early quad picatinny rail. The bottom section can be removed. There should be no need to mess with the barrel nut. Changing gas blocks. Getting out the FSB pins was a mother though. |

I have the 901 MARC. Thanks for the clarification, I'm overthinking the problem and solution. Not having much experience in doing it myself due to lack of experience is a bit intimidating. I know I can remove the lower handguard via removal of the screw, but how about the upper handguard ?
I 'd love to keep the folding sight assembly but thats a nonstarter now. |

The lower rail should be like the 901 LE. Remove the screws. On the bottom rail, close to the receiver should be a hole and tab to push. Push the tab down (up towards the barrel) and push the lower rail forward. Assuming the MARC is like the LE rail.
You will not be able to remove the sides and top rail. Those are integrated with the upper receiver. The only option I can think of if you wanted to keep the FSB would be see if Clint at Black River tactical could tap and custom insert the FSB. I don't know if he does or would do that. The downside is you have to figure out what port size you want and is not very easily adjustable. http://www.blackrivertactical.com/concrete5/customtune-gas-port/ The FSB sight is at a weird height with the rail. The rear sight is a Troy medium height sight. Troy will not sell an individual medium height front sight. I have been too cheap to buy a whole set of troy medium height BUIS. I have read in other forums people have problems sighting in standard height BUIS due to the rail height. Maybe someone else has found an alternative, hoping so. |
