[ARCHIVED THREAD] - Wolf T91 Uppers?? (Page 1 of 2)

Posted: 6/29/2018 12:16:39 PM EDT

Posted this in GD, but didn't get much traction, so thought I would post it here.

These Wolf uppers have been out for awhile now and are getting good reviews.

Now the SBR uppers are out and I am thinking about getting one.

The big difference is these uppers are cheaper than most piston uppers and supposed to be based on the Taiwanese T91 military rifle.

Who has one? Do you like it? Any reason not to buy one?

Just finished this build.

Only 200 rounds through but no issues with it.

The first upper I received was out of spec; it wouldn't fit on any of my lowers. I contacted Wolf and received a return label within hours. They shipped a new upper the day they received mine.

I have the 16.5 inch version on an Anderson lower. Have about 750 rounds through it. Never had any issues.

I don't have one (yet) but I'm planning on getting a 14.5 The 12.5 and 14.5 lengths have a different, thinner barrel profile. If that helps.

I thought the 12.5 and 14.5 barrels had the same (lighter) profile and the 16" had the heavier profile?

That would get my attention. Lightweight 14.5" P&W handle well.

Any way to buy replacement barrels? Seems like a fun upper to use for a registered full auto receiver... but it'd be comforting to know if there's a source for replacement barrels.

I finally got to run my 12 inch version using winchester whit box I had appeared to be a couple of soft strokes . Now I ran only a hundred rounds though so it will be interesting to see what it shakes out like

I have not seen any replacement barrels yet, but if I know WOLF they will make them available. But I can attest to the fact these uppers do make good uppers for full auto lowers and RDIASs. Here is my experience in a video review. The opening shows full auto fire in slow motion and real time, then skip to 18:00 to see just how smooth this upper is in full auto. At $500, the whole upper is cheaper than a lot of other replacement barrels for some of my other full autos. https://www.youtube.com/watch?v=kiRybiOHB8k

T91Tacial has gas blocks that will fit an AR barrel. The barrel nut is different on the Wolf A1 upper, but it's the same size as the one on an AR.

Interesting.

The one you linked is for 18mm (0.709") gas block journal, not 0.750".
The gas port is also further forward relative to the gas block shoulder than an AR barrel.

Here's the right one:

I have read that these uppers do not have M4 feed ramps. If I place this on one of my SBR lowers that has M4 ramps, I will have feeding issues, correct? I would like to get the 12" upper but it's useless to me if it won't feed well.

feed ramps are all in the upper - you'd be good to go.

Here's a nice graphic LaRue Tactical put together:

M4 barrel extension with non ramped upper receiver is ok, you just need to avoid ramped receiver with a rifle barrel extension

Thank you very much for all of the graphics. I believe I would have the rifle extension with this T91 upper and M4 feed ramps on my lowers which is not recommended. I will double check though.

Lower receivers don't have feedramps.

All of that is contained in the upper.

what Findsman said: feed ramps are ALL in the upper receiver - lowers are all the same in that they do not contain any feed ramps. You will have NO compatibility issues with the Wolf complete upper and slapping it on any AR lower..

Ha! no worries, my brain discombobulates stuff that I know better too. Go for the Wolf upper, it's nice and a fun little variation on the same-old.

I have one. I like it. Its my first and only piston upper. I had to go with a tall front sight to get it to zero. Wolf actually supplied it with the upper. I don't know it they got that straightened out yet ... I have no regrets. I cleaned it well lubed, and shot it . Couple of hundred rounds through it, No problems or stoppages....WarDawg

I have not shot it yet but slapped it on my SBR lower with a UCIW stock and YHM BUIS. It's a little front heavy but seems decently made. Piston area was well lubed but the bolt was a little dry, IMO. I prefer the piston retainment design better than my Sig 556, more idiot proof. Can't wait to shoot it.

Just finish building mine with all the parts from t91tactical. Sean is a good guy!
First time drilling/pinning gas block and drill 30 degree tilt gas port on a cheap anderson 14.5 barrel.
I think I did okay.
Took it to the range this Monday. Fired 200+ rounds. No issue with factory ammo. She does not like my hand loads.... FTF.

Next step, pin and weld.

Because a military rifle needs a bayonet! LOL

I pick that barrel because almost all 14.5" barrel with carbine gas system has that M203 cut.
I think T91 looks better without the M203 cut.

I just had to do this. Pins were so tight I had to hammer them in on the lower.

Hopefully the new upper is better.

I wound up doing a P&W on a 14.5", and it lives on a PSA lower. Using a LaRue rear sight, and I did not change the front out (and am not sure if I will need to, we'll see). I love the front sight hood; the irons with the LaRue rear are sweet enough that I might not even put an RDS on top.

Maybe Im not looking in the right place, but I couldnt find that rear sight on Larue's site.

So is the T91 front sight compatible with rear sights made to line up with F marked fsb's? I see that youre not 100% sure so the question isnt directed towards you in particular.

Seems to be, but I know it's a common complaint. The adjustment dial isn't perfectly flush in the front sight hood, but it doesn't bother me any. YMMV.

The T91 uppers come with a flat top AR compatible FSP. If you use a T91 carry handle or T91 "simple rear site" you may need the shorter replacement FSP sold by T91 Tactical. Should be good to go.

adjustable gas block for supressor?

Posted: 5/28/2019 11:58:02 PM EDT

Hi OP- I posted this up a couple of days ago in the hog forum, but it’s the only pic I have of my T91 as well... I’ve had mine for a while and have only run it suppressed, now with a H3 buffer. Standard buffer suppressed it was over-gassed and encountered some failures to eject and feed. Heavy buffer and it’s been flawless for several hundred rounds. I like it, FWIW...

Edit to add- take care to make sure the piston can still have clearance to be removed if you install a new muzzle device. Mine just barely clears a 51T and takes a little finesse to get it back in once removed. I’d like to have it set up for some other cans I have using a YHM QD mount but it’s a larger diameter.

Old thread, by a bit, but took my new T91 upper out today along with a KS47. First two rounds there was a failure to extract, after that nothing but smooth running for the rest of the 60 rounds I put through it. There was some slight wear at the top of the upper, nothing major, just some small dings I assume were from the initial use, and the factory grease on the piston system smelled a bit, but it ran great! Next I’ll zero the sucker and see where it goes. :)

I work with several former .mil from Taiwan. LOL at least one guy wants one after I showed them the uppers. Says in basic a TW version of the M16A1 was what they carried and that the new rifles were heaven in comparison.

At least at the time when my friends were TW.mil, Taiwan had a mandate that everything was piston. Even their M16A1s has been converted/remanufactured as piston. It’s a thing with them.

T91 uppers are GTG. I talked to couple of guys at the range I go to and the owners talked how reliable the uppers worked and for the price point they brought at.

Atlantic Firearms has 16" A1 (T91) uppers @ $449.00 - I guess this is the going price?

Thank you! $450 is what I paid for mine (14.5" P&W); usually they're $500, I'll gladly save $50.

Mine is on a PSA, and it fits quite well. Not excessively tight, and no wobble. YMMV.

Thanks - sorry for not reading above. I also thought your sight had an elevation knob.. oops. I like LaRue product quality and fit.
Just ordered a 16" T1 upper from Atlantic Firearms.

Questions:

Is the T91 bolt the same as the M16/AR15?

Any issues using an A2 rifle stocks?

Posted: 9/27/2019 2:14:34 PM EDT

[#50]

Here's a question - the descriptions I've read of the 14.5" say with the muzzle device overall length is > 16". Does this device come pinned and welded, or is that something I'd need to have done to make a 14.5" legal to mount on a regular lower without a stamp?
