I bought a Colt 6945. Why? Because I wanted one. Good enough reason for me.
I ordered the rifle Feburary from Gun Gallery. In September the tax stamp finally came back from the ATF and I picked it up. The staff at Gun Gallery were friendly and helpful, so I would purchase from them again.
The Colt 6945 is a short barreled rifle (SBR) version of the Colt 6940. This rifles 10.3 inch barrel is the main difference from the standard 6940, and is why it is a title II firearm which required me to pay a $200 dollar tax stamp to get it.
The 6940 series of rifles have a monolithic upper with a removable bottom rail. The barrel uses a proprietary barrel extension and gas tube. Shawn and others have reported that their 6940s have superb accuracy due to these changes. Personally I don’t plan to try and use this as a precision rifle, so its no difference to me.
The best thing about a short barreled AR15 is the pure modularity of it. I can easily swap upper for various barrel lengths and calibers.
So I really like my 6945.
Since getting it I have run six different uppers on it. That is one of the great things about a SBR AR15 is the ability to easily change the uppers for difference barrel lengths and calibers. I also swapped out the stock trigger for a Geissele Super 3 Gun trigger.
I have several Geissele SSA triggers and I highly recommend them. I wanted to try the Super 3 Gun (S3G) trigger, so I picked one up a while back. First it was installed in a LMT lower, where it would often double & rarely fail to reset after a shot was fired. So it was quickly removed from that lower(I have had other issues with that lower before). When the got the Colt, I went and tried the S3G trigger in it. Now in the Colt, the S3G trigger worked fine when shooting offhand or from the bench. However due to the very short reset, when I was firing from a bipod I experienced unintentional doubles. This trigger might be great for someone who wants to bump fire, but the reset is a little too short for me. I wouldn’t recommend the S3G for any serious fighting rifles, but I do recommend the Geissele SSA and the Colt 6945 as they are awesome.
