Type 81 mlok hand guard

Thanks for posting , I'm definitely interested, wish they would just make railed dust covers....
Wonder how the accuracy is when a red dot/prism sight Is mounted on the handguard ( that far forward) ?
Rumors floating around have hinted that Sigmaco has one in the works.... however i cant imagine it being less then 300 dollars.
Hey, when will your side rails be back in stock?
A solid railed dust cover.... THAT I'd be down for!

would a railed dust cover even hold a zero worth a damn? it's more solid than the sks dusk cover but still...
Cross posting this from the main Type 81 Pictures, Range Reports and Photos thread.
The target is an IDPA target. (the 'down zero' circle is 8" diameter) The aim point I fashoned from 3/4" x 3/4" black target patches, and works such that the Aimpoint H1 dot nicely covers the black square at 100 yards.
So Cole's notes on the TI handguard holding zero sufficiently to mount and run a red dot? No bueno.
I suspect that the tiny fasteners are not up to the job of securing the top of the hand guard in place for repeated firing cycles - even locktited.
I'd be interested in seeing a high speed slow motion video, but I imagine its like watching a cowboy trying to ride a bull.
The below photo shows a 10 round group (circled in red), followed by taking the top rail off to simulate cleaning.
I fired another 10 rounds on another target with the irons, then put the rail back on and fired another 10 round group at this target (circled in blue).
The MPI shift is obvious.
It is probably worth pursuing further (maybe drilling and tapping this rail and hand guard for larger, more robust fasteners), but as it stands I wouldn't recommend buying one thinking it is going to perform from the go.

Thank you for that! I was really on the fence deciding if I should get the handguard for my folder, but was skeptical about it holding zero after removal for cleaning. Saw another similar post on FB today where the poster said "it totally holds zero, I just had to adjust windage a couple of clicks after I took the cover off", which seems similar to your experience! The handguard does look nice though
If the facebook poster saw only a couple of moa, and depending on the ammo used and the amount of rounds in their group, I could see a conclusion drawn to suggest that shift is minimal.
It would be interesting to see their results.
This was my one and only test of this and I thought it was pretty conclusive right out of the gate with 10 round groups, as that MPI shift is around 8 moa right and 2 moa up vertically.
Now on to bubba up this rail...

Distance was 100yds. Shooting was from a bench with improvised bag rest. The aiming square is 2.25"x2.25" and the aimpoint 2 moa dot nicely covers the dot. It's tough to tell for certain, but I believe my benched hold was comfortably within 2moa, and probably around 1 moa if I had to take an educated guess. I've worked over the trigger on my T81 and it is a very smooth 2 stage that breaks nicely at 5lbs. I prefer it to the stock trigger on my APC223 and would compare it fairly favourably to the trigger on my Swiss Arms carbine - to give some context to it.
As an aside,
'Ganderite' on this forum did a review of this Mesko Polish surplus and had terrible results, so I was quite pleasantly surprised on how it is shooting.
I haven't shot this T81 for at least 5-6 years, and I don't remember how this stuff was shooting prior to putting on the handguard, but I am wondering if the installation of this handguard has changed the harmonics of the barrel for the better, as the lower portion locks up solid. Definitely more testing is warranted.

I was curious to do a “real world test” with the sigmaco aluminum handguard. Since a lot of people have those. I did a 5 round baseline group and then performed the handguard removal/reinstall test 3 times (5 shots each) with no perceived shift in zero at all.
The baseline group was 3.75in and the subsequent groups were each between 3 and 4in. The perceived center of the group was roughly the same for all 20 shots.
Now for the details for those who care:
Optic: known good 1x open reflex red dot
Distance: 75yds
Wind: Consistent low breeze - 100% sure this did not affect results.
Ammo: Chinese surplus all 20rds from the same paper wrapping
I made sure not to move or even bump the optic during handguard removal and reinstall
I made sure to mix up the screws each time to ensure screw placement was random. They were also tightened in a different order each time
Screws were all started until there was resistance, then screws were all tightened
I “torqued” the screws by hand each time to ensure this is as realistic as possible to the average user
The upper handguard was squeezed down towards the lower guard (by hand) while tightening the screws all 3 times
Conclusion was on the sigmaco guard, on this T81, it doesn’t make a lick of difference taking the guard off as long as you install it in a logical way with gradual tightening of the screws. YMMV of course.

I finally have some time and iam going to install the mlok hand guard 2017 fixed stock T81
Did you guys use a torque wrech?
I couldn't find anything in torque values in the instruction pamphlet
How many inch pounds?
Or just "hand tighten" them ?
Also is blue loctite mandatory?
Thanks in advance

I wish that it didn't require tools to disassemble, I modified mine to allow the stock gas tube cover to be used so it can be taken apart for cleaning without tools
makes sense and it looks good. what mod did you do to the OEM upper?
Misleading conclusions on the “not holding zero”.
Sounds like it holds zero but after removal needs rezeroing. That’s a huge difference from it being wobbly and unstable during shooting and groups opening up!
I love my T81M and think I’ll grab a set so I can throw on some optics and fold the stock! TI has these awesomely priced.
