@ the OP:
If you REALLY want the perfect Tactical SKS, buy on, take it out of the box, clean out the cosmoline and learn how to shoot the thing.
It is as reliable as a rock.
The sights are wide enough that you can see them and use them in low light.
Most maintenance problems are caused by using crappy old corrosive-primed surplus ammo. Feed the thing fresh, noncorrosive ammo. Better yet, handload for it.
It was designd to work in all weather and climatic conditions, hit a man-sized target out to as far as 300 metres.... and that is ALL that it was designed to do.
The PLA thinks rather highly of the as-issued SKS.
So does the PAVN and the FLN and the SP and the Viet Cong and a few other organisations. You really might consider THEIR points of view on the matter.
"Building" a bog-stock $169 SKS into a $400 tacti-kooool special will set you back $800 in parts. At the same time, it dos not IMPROVE the rifle one tiny bit; if anything, it lowers the utility (the essential usefulness) of the rifle. Save your money, friend, buy a spare rifle.
A couple of further points: semi-auto rifles in Canada are limited to 5 rounds. Attempting to source an illegal 20-round magazine would be a violation of the law AND of forum rules.
If guys are making fun of your shopping list, you might try to improve your own English: THAT is where the problem lies in this department. Spelling, punctuation and terminology all are important. There are some posts on here which are so poorly-worded that I have trouble even trying to undrstand what the Poster is saying. Of course, I have ONLY been collecting and working on these things for the last 50 years, so likely I don't know as much as the clerk at the tactikool store.
Your buddies over at Red Rifles have tricked you into coming over here to Milsurp because they know that this forum is about restorng and preserving original military rifles. They were hoping that some of us (such as myself) would get all out-of-sorts with you and tell you what we really think. We won't do that because we are gentlemen here...... although we might poke a little harmless fun at poor English usage and silly questions.
Hope this helps.
