Its a long gangly setup for people who want to run and gun sub 200m. Which id suspect is a vast majority of the Type 81 market.
Well, as far as "long" and "gangly" go, the SR is almost exactly the same size and weight as an SKS. Sitting side to side with the butts on the floor they're almost exactly muzzle to muzzle, and an SR with no sling or optic weights in at 8.33lbs while an SKS right there too, give or take a quarter lbs heavier or lighter depending on the rifle.
The P04 is pretty heavy at 1.3lbs so that gets you to just under 10 full configured for the SR. That's getting heavy but it's honestly pretty standard.
For the record a stock SE fullstock weighs in at 7.12lbs while the LMG with no bipod is 8.42lbs. No mag included in any weights i've given, the source of all of which is my postal scale. The pencil barrel on the SE is doing the heavy lifting in the difference there.
So while the SE will make for the handiest rifle by a good margin especially when you remove the silly grenade sleeve the SR is really quite manageable too, unless we're also going to call the SKS a pig which it really isn't.
The PO4 optic on the SR works really well for quick shooting on steel since it's essentially a commie ACOG, and the muzzle brake really keeps the muzzle down. I didn't do much running but i've shot several hundred rounds off hand at this point and i'm a fan.
I definitely will still get an SE and remove/swap and bunch of stuff on it if and when they show back up since I like the T81's in general and i've already pretty far into this platform with all the mags and stuff, but the SR is staying in the configuration it's in now.
