View Full Version : Geissele 16" CHF
I've been reading about problems with the Geissele 16" CHF barrels. Molon stated in his review of the barrel that the gas port was .062 and IIRC that review was atleast a year ago. I see that on the Geissele website they list the barrel having a .078 gas port. Does anyone know if they have fixed previous issues with the barrels, are the barrels good now?
I have (5) Geissele Super Duty uppers. Some are full Geissele rifles, some are just uppers on other lowers. They range from 10.3-16”. I shoot them all at least once a month and at least 100-150 rds per training session. They all shoot splendidly and I’ve never had a single problem. My good friend owns an 11.5 SBR and a 10.3 URGI and his experience mirrors mine. There was a batch a while back with short chambers and undersized ports. It’s fixed. If you get one and it doesn’t work, they’ll fix it. Geissele builds an excellent rifle. I wouldn’t hesitate to try one.

If I remember correctly, there were issues with the barrels that were sold individually as opposed to the super duty uppers/rifles

Undersized chambers were in complete guns and uppers. I don’t believe I saw any complete uppers with gas port issues.
Stand alone barrels had gas port issues. I don’t know if any stand alone barrels has chamber issues.
I put a few more mags through my 11.5 today. Haven’t really shot it much since it got repaired for the chamber issue but it’s functioned perfectly through several mags so I’m confident in saying they fixed mine.

I bought a stand alone barrel about a month ago from a company that sells a lot of barrels so I think it's probably a newer barrel. Maybe I don't have anything to worry about. I have not built the rifle yet.

The problems are not just limited to the stand alone barrels.

I bought a holly grail rifle, mine has been very accurate and very well gassed. I hope your runs just as well. It shocked me to hear of all the issues, I would have bought another upper if I didn’t hear of all their issues.
Keep us posted on your guns guys, good and bad. I would hope they got their shit together.

On the bright side, I got a mk16 blemula for about half the regular price and I can not find a single flaw on it. It's beautiful.
Seems like most blems are rarely blems. If at all. I wondered many times if they just have overruns and want to score some quick cash, werks!

All of mine too, and a few dozen other complete guns and uppers. No mods or "improvements", GTG ammo.
I had the same concerns with my 14.5 SD complete upper and it turned out to be perfect, other than the weight over my BCM and DD's it's become my go-to. Had it out this weekend in 17 degree temps and the snow and the thing just ran, about 1200k rds with no issues what so ever thus far.
N of 1, I had a new M4 I had to mortar probably a half dozen times in the first week I had it issued.
Pretty sure Colt, 2011.
G isn't the only company that puts out an occasional dud.

1200k, huh? So 1.2 million? That's impressive.

Yes I'm an impressive guy, as this is the internet, and I am a part of said internet where people never make mistakes, it was 1.2million maybe even 1 million, 2 hundred thousand and 3. The only rifle ever to go over that in round count that I am aware of was a Palmetto State Armory upper with that sweet, sweet FN barrel made to the exact specs as BCM (According to some guy on TOS), and now if you need me, I'm going to go back to writing speeches for Vice President Harris
I decided not to use the Geissele barrel for this build. What attracted me to the G barrel was the contour and that it has 1/7 twist, CHF, chrome linned, and 5.56 chamber. I like the taper contour. I really like the contour of the Criterion Core but it is 1/8 with Wylde chamber. I took Molon's review of the Geissele barrels into consideration and I also decided that I wanted the gas block pinned. After talking to the local gunsmith about the price of pinning the gas block, I decided to get a Daniel Defense barrel. I got it for the same price as the stripped G barrel but the DD barrel comes with a pinned gas block. I know there are probably other options or ways to go about doing this. I guess what I am looking for is a 16" CHF chrome lined 1/7 twist, phosphate finish, 4150 V, 5.56 chamber with a taper contour like a Criterion Core or Geissele taper profile (not a lightweight or pencil), and comes shipped with a pinned gas block for less than $400. The Daniel Defense barrel I am going to use is a government profile but fits all the other criteria. Also I hear that these barrels are fairly accurate. I think Black River would be another option but the hammer forged with a pinned gas block cost more than the Daniel Defense barrel that I purchased. Next time I might use a Black River barrel.
Wait until Noveske goes on sale & buy that

PBs gun even shot that Fukked up AAC ammo longer than any other AR before malfing. It's a good gun.

Which AAC ammo vexed you guys? I've got some of the 77 sitting here unshot....

The 77s. I have some real time in trying to un-screw that stuff. Thought I had it licked at a 1.2 gr powder reduction, but it started malfunctioning again. Back to the chrono, and the ammo is shooting too hot still.

Have you fixed this problem yet? I also have the problem that the bullet is overheating but I really don't know how to fix it.
the bullet is overheating
:confused:
When you say it’s overheating, what does that mean?

I stopped using the AAC powder. I've gone to subbing in Vihta Vhouri N135 instead. I bought some plain jane FMJ 62 gr bullets to load with the AAC powder... loaded very mildly to allow for the random pressure spikes.

How are the bullets performing without AAC powder on board?

I've had the bullets shoot well with AAC powder, but the velocity was too great for gas gun function. I've also had them shoot fine with VV N135 powder.

I knew this response was coming lol. Every time someone mentions Geissele, Molon responds with this post/links.
