looking to get a factory SBR in the near future, and im torn between these two rifles. finding a 6933 right now has been difficult and there are a few places to get the 6943 right now for a pretty good price. I want the 11.5" barrel mostly, but im not too sure im sold on the monolithic upper and the flip up post. this won't be my first SBR but its going to probably be my only factory one and I figure it might as well be a colt.

The monolithic uppers are simply amazing.
I have 2 6940's and 2 6944 uppers. Not to mention a LE901. |
|
I have a 6933 and a 6945. I like my 6945 much better. I like the monolithic rail and flip up front sight better.
|
|
the monolithic rail is cool, but I'm not a fan of the flip up sight. I just bought a 6933.
|
|
For those with Colt 6945 SBRs is there a source for new gas tubes yet? IIRC the gas tubes are straight?
|
|
I'd love to sell my 6933 upper and get the 6943. I listed it on the EE, but never got any hits. I like the mono uppers much more.

Colts monolithic uppers are extremely rigid, and for what they are, lightweight. I can weigh a 6940 upper vs a 6920 upper later this weekend to give you a better idea of how they compare.

Thanks for posting that. Wifes honey-do list is getting in the way of me doing this.

Let's be a little scientific and get some interesting data to compare.
6940 upper: 4 lbs, 8 oz with Matech sight, bare rails. 6920 upper: 4 lbs, 14 oz with KAC M4 RAS, bare rails, and carry handle. 6920 upper: 4 lbs, 8 oz with KAC M4 RAS, bare rails, and Matech sight. 6920 upper: 4 lbs, 6 oz with M4 handguards, and Matech sight. 6920 upper: 4 lbs, 12 oz with M4 handguards, and carry handle. The 6940 is only 2oz heavier than the 6920 with factory handguards, and same BUIS. KAC RAS installed equals it out, but the 6940 has the advantage of free floating the barrel. All measurements were taken with Colt BCG in place, and a BCM medium charging handle. Just out of curiosity, what does the LMT MRP upper weigh? ETA: a 6944 upper (same config as above) with perm'd A2X is 4 lbs, 7oz. |
|
I'm a big monolithic fan so I keep eyeballing the colt mono uppers. I just weighted one of my MRP uppers, equipped as follows:
MRP CQB with 10.5" barrel LMT full auto BCG BCM mod 4 CH AAC 51t blackout muzzle device MBUS pro sights Four ladder covers on the rails Total weight: 4 lbs, 6.5 oz Not quite an apples to apples comparison to a 6945 upper, but close. ETA: Putting an A2 on the muzzle and removing those four ladder covers will drop the weight by at least 3oz, so it will end up *really* close to the 6945 upper in weight. And the MRP still has a heavy barrel profile while the 6945 barrel is gov profile. |
|
id be interested to see the weight on the 6933 upper, maybe an upper swap or a conversion kit could work out for me if I get the 6943. thanks for the input so far guys!

Just weighed new 6933ck
This has a government profile barrel with the front turned down to slim profile. Under hand guards has: C MP 1/7 5.56 NATO weighs 3 lbs 12 oz |
|
I always thought the Colt monolithic uppers appeared to have more girth than necessary so I always stayed away from them; plus i'm not a fan of the flip up sight/gas block combos. They are certainly priced right, though.

The 'calipers of truth' say that the rail of a 694x and a KAC M4 equipped 6920 are the same width.
Both measure 2.325" wide. Obviously, sans rail covers. |

I have called around and cannot find any new 6933ck with the .625 block |
|
|
been a while and I doubt many care, but I ended up going with the 6943. the newer 6933s being hard to track down at the price I wanted to pay and them also having a .750 FSB barrel instead of the .625 made me jump at the 6943 I was able to get for $1280. my local dealer has the form 3 from his distributor going now and hopefully soon I can get that paperwork going.

I own a 6933 and a 6945. I like my 6945 better because of the monolithic rail and flip up sights. I think you made the better choice. (My personal preference of course.)
|
|
6943 would be my preference. With the 6943 and 6945 you get a CHF barrel. I personally prefer a longer, slimmer hand guard but the 694x SBRs are just too cool to pass up.
|
|
|
Never heard of any Colt (other than Colt Canada) having a CHF barrel.

This thread has been very helpful for me. I wanted a 6933, but after reading this thread I bought a 6943 today. I guess the 2 deciding factors being the fold down front sight( plan on using red dot and didn't want a front in the picture all the time) and the picture thread here of the 6933s that show most with rails.
