Hey guys
I have a pair of colt le 6920’s. On at least one of them I want to have the barrel cut to 14.5 inches an have a longer A2 type flash hider permanently added. So who is the best person or company to have do the work? I dont want to go mid length. And want to keep the colt factory barrel. So who do you guys recommend?
Thanks
I will be adding a DD omega X rail for my mid length desires
Iv had good correspondence with ADCO
I feel like there prices are fair.
Thanks, I went to their website. Maybe I am missing something, but all I need is the “muzzle device” work? Its only 30 bucks I think. Is there additional work that needs to be done? Will they cut the barrel, and permanatly add the extended A2 all for only 30 bucks? That doesnt seem right. So what am I missing?
AHHH nevermind spoke/typed to soon. Looked again and answered my own question
I think it might end up being

Id email him and find out for sure. I know he has strict ordering and shipping procedures.
** Edit also if you send a complete upper theres a disassemble/reassemble charge.
I guess I do have another question related to this. By shortening the barrel length will I potentially run into issues. I understand 14.5 inch will be more optimal for the carbine length however 16 inch has not proven to be problematic as of yet. Will this potentially harm the reliability of my rifle?
You shouldn’t have any serious issues cutting it down to 14.5, With Carbine gas length you’ll be alright, Ive heard of some issues with mid-length 14.5s but I don’t personally have and experience with that set up.
Before you proceed with anything id recommend using the search button up top. More often then not you’ll find a wealth of knowledge. Sometimes you can revive a similar thread with a more specific question.
To be honest with you, Id keep the 16" for a while or depending on where you are if you have one 16"… SBR the second one, that way you don’t have to perm the muzzle device. At least in my situation that’s optimal for me because initially my experience with ARs was military related so all I knew were A2s so I switched a few around…
Ive become very fond of battlecomps lately, but that’s besides the point.
It seems like a lot to spend for 1.5 in. less bbl length. IMO.
OP
With all the research I’ve done here, I’m sendin work to 2 people.
ADCO
Marvin Pitts
ADCO for a couple builds that need to be finished and Marvin Pitts for some barrel work.
ADCO prices can’t be beat in my opinion. I’ve been looking for a few months now. They have some of the best work and the lowest prices around.
And cutting on a factory Colt barrel is a SIN!
Just removing the excess
ADCO is good.
I’ve heard great things about Marvin Pitts. His work on the SCAR system is remarkable.
Though I am not as religious as markm I think you are spending money needlessly. I find it hard to believe that you can tell an honest difference between a 14.5" and a 16".
Not to mention you are cutting on a factory Colt barrel and then perming flash hider in place.
Stick with the 16" or get a true SBR.
Well the thing is I have put a few thousand rounds through one of em while I was laid off. I’m back to working and ammunition will be much more available. I will be putting more rounds through it per year. Ball park of, 7-10,000. Now I know that is not nearly as much as some others are doing but after looking at a chart that was on here. I noticed that that 1.5 inches apparently was far less harsh on everything. Or am I looking to far into it?
A VLTOR A5 kit, and/or LMT Enhanced Carrier, and Bolt would do more to improve function than chopping off an inch and a half from your barrel.
That would be money better spent.

There’s always Specialized Armament.
Thank you to those who have replied.
After looking around and talking to a few people on a few forums. I’m not real sure I actually gain anything by cutting the barrel outside of asthetics. I dont see I gain any reliability, as 100% reliable is 100% reliable. Havnt found a single real world number or round count that really shows if my parts will actually last any signifigant amount longer. Perming a FH I will still have the same overall length, only with slightly less velocity. Also while I have no intention of changing the FH I may want to change hand guards and from looking at the ones I’m interested in removing the FH will be required. I think I will go with what others have suggested and just leave it be. I suppose its possible I might gain faster shot times but even then I think the real world difference wont mean much. After several hours of looking and reading I can see the thinking behind it and better understand the timing issues. I think for now though I’m not going to worry about it
If you decide you want to go with a pinned 14.5 I would strongly recommend looking for a 14.5 Colt barrel and then selling your barrel. M4 barrels can usually be found NIB for $250 - $300.
I also believe that ADCO charges to disassemble and reassemble your upper which adds a lot of $$$ to the deal. Either way, I think you would come out cheaper by swapping barrels, and you will know for sure that it has the correct gas port size.
