Colt 901 Great rifle

Pappy1600 · August 10, 2012

The rifle was not supplied with either the conversion block for the mag well nor the upper reciever adapter, I did try to fit a 6940 upper on the lower and it matches up to the rear pin but the way the front pin is designed it sits much lower on the lower receiver and is at a angle, so you would need the adapter in order to secure a 5.56 upper. From what I had seen if you do install a 5.56 upper when removing the rear td pin and folding the upper forward space is very limited, might only be able to remove the BCG. I am surprised that Colt did not ship the adapters with these rifles, maybe since it was the first run that was shipped may have played a part in it, also I have no idea how to even order them, no information was provided by Colt.

I actually know nothing of how the CM901 works. Is the adapter attached to the upper? Or is it a 3rd part you need to carry around? The quick change feature isn't looking so quick any more.

Here is a picture of the upper adapter.

Here is a video of how it is put together

I do not plan on switching my uppers, I wanted a .308 single purpose rifle, I have other .223/5.56 rifles to use if needed, I can see that it is a nice feature but for me it does not matter if I have the adapter or not.

That sure stomps the hell out of a T/C Contender or Encore! <thumbsup>

I don't mind the adapter portion. It allows you to use already produced AR15/M4 type uppers. That is a huge bonus!

I don't like that they couldn't figure out the buffer/buffer-spring difference. Mil and LE guys are notorious for losing and breaking things. The less amount of parts we need to be responsible for, the better.

I still love the rifle. I have no doubt that, in time, a new buffing system will come available.

Pappy1600 · August 11, 2012

From what I have been reading around on different sites, I am hearing that the weapon is functioning with the 308 buffer with 5.56 uppers. I have yet to hear any issues resulting in this configuration, if I hear otherwise will let you know. Now I want the adapter just to see if the 308 buffer does work with the 5.56 upper. Just need to figure out how to get one. Guess will have to call Colt up and find out how much they want for one.

Robocop1051 · August 11, 2012

It would be nice if they made a polymer adapter vs the aluminum model. The weight is beginning to look excessive.

I also see no reason why a 5.56 upper can't be configured to use the 7.62 buffer system. Just make sure you have plenty of gas going through the gun, to push the heavier buffer and spring. I'll bet a 5.56 upper works really well with a sound suppressor on it. Just a guess...

Pappy1600 · August 11, 2012

I am sure in time, someone will make a polymer adapter, yes the weight on this rifle is up there, the way mine is set up right now weighed in at 12.2 lbs , thats no joke! send me a can and I'll let you know ;D

No cans to be had here, just what walks around the house and whats in the fridge!

Went to the range today, Sighted in the ACOG, using 147gr hand loads, just had some 165gr and 168gr Hornady's come in today, need to see what they will do.

I'll have another glass of Kool-aid please!

The trigger SUCKS, ordered a SSA-E, can't wait for that to get here.

unforgiven · August 16, 2012

Nice shooting brother looks like you had a good time. <thumbsup>

Pappy1600 · August 16, 2012

This Coolaid ain't half bad, got ice? <thumbsup>

Pappy1600 · August 17, 2012

The nice UPS man dropped off a present today!! the good folks at Geissele had sent my new SSA-E trigger for my 901! Last time I ordered it took a couple of weeks, this was less than 3 days! needless to say it was installed in record time, only one issue, the pins supplied by Geissele were shorter than the standard pins, so I just kept the originals. Will give them a heads up. What a nice trigger, can't wait to take it out on the range.

<lmao> <laughs> :hornet:Play nice brother Rob. :o

Pappy1600 · October 22, 2012

Picked up another scope for the 901, it is a Leupold Mark AR 3-9x40mm T2 with a LaRue 104 mount, this will be in addition to the ACOG, Wanted something for some more precision shooting. Hope to get it on paper soon.

Pappy1600 · December 12, 2012

Hornady 168 gr. Amax, with Varget, 100 yds. Not bad for a battle rifle.. The SSA-E trigger I installed is awesome!

george_995 · December 12, 2012

Very nice, I was looking at that Leupold vs. a fixed power SWFA 10x scope. I am thinking about the variable power in favor due to hunting applications. <dontknow>
