Personally I don't think this is Type-81; the magazine, the butt stock, the muzzle are all different. Do you have any link to that gun?
The best route I see for Correcting the range issue for the PLA and it is a issue IMO, would be to either introduce a modernized Type 85 with improved ergonomics, Rail interface and cut down barrel. as the 7.64x54R round offers superior range to the 7.62x51mm. Or introduce a 7.62x54mm variant of the QBU88 series. then introduce a 7.62x54mm R calibre Medium Machine gun based on either a reduced weight Type 80 MG or a scailed up QJY88 feeding form the same round along side a reduced weight QJY88 for Infantry and Airborne.It has turned the Type 81 into a real Battle Rifle....
I hope that this weapon becomes eventually widespread in the PLA, even if only for the special forces, to help to address the lack of lethality on long ranges coming from the 5.8x42 caliber standard.

相对比装甲车、无人机这类大型装备,枪械对人的吸引力还是大很多的。尤其是国产枪械。本次警用装备展上,81式突击步枪终极改进型正式亮相。新枪编号CS/LR14,主要用于外贸。其枪口消焰器、枪托、弹匣、瞄准具全部更新。外形相当时髦,很有眼前一亮相的感觉。

Upgraded QBZ-03 in that same exhibition. They put scope like that on it instead of red dot or something similar usually found in rifles.... it's supposed to look cooler?
I was curious, so I did a supplier/product search on Alibaba.com for Picatinny rails and optical sights, and wow, I got thousands of hits out of Mainland China. Of course, as you said, many are knockoff products, non-military grade, or suppliers with no R&D capabilities.
BUT.
The sheer number of suppliers and products on offer tells me that a robust industrial base is there for firearm accessories, and should the Chinese military opt for fancy rails and red dot sights in the future, it'll have no problem whatsoever arming the troops with something decent.
