All-New: Type 81M

There's 60 minutes in a degree.

Goes to show how quickly things can get out of hand optic wise with a misaligned trunnion even at TIs spec. Aligning a basic / old school optic like a Vortex Crossfire, PSO's, POSPs, Russian red dots on a bent Type 81 in a worse case scenario can gobble up at least 70% of your windage adjustment. But then again lots of nicer optics have like 100 plus MOA of adjustment too.
 
Received my fixed 81 today, everything's great except the LOP (maybe an inch short). How can I make it longer without supporting those greedy Sigmaco parts scalpers?

Those kick eez spacers likely works but I'm concerned about the concave shape on the butt

Stack a couple of Maxi pads.

:evil:

GP25 style buttpad will give you some extra space.

UTG buttpad works very well.
 
Picked my fixed-stock up at the post office yesterday. The good news is my muzzle brake and sling were in the box (plus the two 5/30 mags). The bad news: only one of the two "spare 5/5 magazines" I ordered was in my box (I'll send off an email to TI today). With all of the comments in this group I checked for a "bent stock" and yep - very noticeable when looking down from the top. With the barrel pointed forward, my rear stock is canted to my left. Not sure if I would have immediately noticed it, except for I was looking for it as soon as I opened the box.

Gun shoulders just fine and I took it to my local range (25 m indoors). We can't shoot anything that sticks to a magnet, so I put through a couple boxes of my handloads featuring Berry's plated bullets and BLC2 powder. All rounds went BANG and the gun cycled well. The short length of pull doesn't bother me (I'm 6' and over 250lb) but wearing my ear muff hearing protection makes it hard to get a good sight picture - definitely need those orange foam ear plugs when shooting this.

The sights were good out of the box left/right with my hand loads. I had to crank the elevation up to "5" (I assume 500m) to get close to point-of-aim / point-of-impact but again, handloads at 25 yards.

Next up (after emailing TI) is to take it to my outdoor range and put through milsurp ammo at 100 yards. Definitely a fun gun to shoot and love it just as much (so far) as my SR and LMG. I should probably buy more ammo.

Thank you TI for bringing these in to Canada. In my not-so-humble opinion, all of these Type 81s are well worth what I paid (YMMV - I'm biased!)
 
My Samson underfolder cheek rest came in, should fit nicely on the Type 81. This design lets the stock still fold and lock closed

Thats not how optics work... once its zeroed its fine out to infinity.

That actually is how optics work. This is particularly why side mounted optics are not popular. Keep in mind that the effect happens at long range so people shooting distances say out to 400 meters may not notice. People with a side mounted scope on a Winchester 94, as an example, will notice this effect even at short range because the scope is so far off the bores center.

My fixed stock is the same, barrel straight but stock with the bend. My fixed stock from the original 2017 shipment had the exact same bend.
 
Plot twist on the order numbers, for those of you who assumed that all orders are sequential. I placed my order on Mar 14, and was in low 28***. A friend of mine just put in an order this morning and his order is in the high 25***. Neither of us had ever ordered anything from TI before. And no, he didn't make a typo, I had him double-check. My best guess is that TI keep some sort of unconventional order numbering system to conceal how many orders they actually received

Where talking about 2 different things. The rumor im trying to correct is that a reciever mounted optic centralized over the bore of a gun with a canted barrel WONT observe a progressively increased windage shift so long as the optic was zeroed. That seems to be the big concern online rn regarding misaligned Type 81 trunnions.

My 2017 Type 81 side folder is about as bent as they get, 100m POI was left 5ft left of POA before zeroing. The red dot was successfully zeroed with only a half turn on the windage knob left. When i shoot 200m the POI isnt magically 5ft to the left again.
