55recce you clearly have no idea what you are talking about so just sit this one out.
As for the adapters I have been running the Hical adapter since they first came out over a decade ago and it continues to perform 100%.
I did the install by myself and the only thing I had Hical do was cut some M4 style feed ramps into my rifles chamber face to assist in feeding from assorted magazines, luckily their shop is local for me so I didn't have to mess around with shipping.
My bolt has had both sides of it milled down so I can insert full magazines on a closed bolt.
Here is a old video showing how the rifle just chugs along with zero issues.
More recent video and she shoots just fine at 100 yards with a cheapo NcStar 4x which has now been replaced by a 4-12x40 Nikon Buckmaster to make things even better.
I've had a few SKS-D's over the years and sold them all as I wasn't willing to butcher, but I didn't hold back grinding up this Tula refurb to have a detachable magazine 10 round rifle.
I've fired thousands of rounds of mostly surplus out of this rifle and the barrel is still in immaculate condition, but that said I tear the rifle down to every little piece anytime it has ever seen corrosive ammunition.
Wood or synthetic ya just can't go wrong, if you have any other questions feel free to ask away.
