Purist will be purists.... traditionalists will be traditionalists. Owning both a highly modified SKS, and a stock one. My advice is always to buy a stock SKS and shoot it as is (if you havent extensively shot one before) ..... THEN; if you find there is something you want to improve, improve it.
For instance, on what id consider is a highly modified SKS below:
it started out stock
but after shooting it, i realized there was areas that i wanted to improve to better fit my needs.
I did away with the short uncomfortable wood stock, and added an adjustable length of pull one that had a pistol grip for improved ergonomics.
I did away with the clumsy box mag and stripper clips and switch to tapco detachable mags.
Struggling to use the horrible iron sights, I added a rail and scoped the firearm.
****Of course, this was all based off my personal preference and experience with the gun. Many SKS owners in this forum may have no problems and be perfectly content with the SKS as it already is. ****
After shooting it some more, and learning what worked, and what didnt, what was garbage and what wasnt lol, I made more improvements..
As I learned more, tinkered more, I improved it more.
As it currently stands.
But thats not all! lol with some inspiration and know how that ive gained from other projects, and another CGN'er. I plan to do away with the current Archangel stock (which ive really enjoyed), and carve out a custom SVD stock in wood.
Note: At no given time, did the overall price of this SKS reach 2/3rds the cost of a CSA VZ 58.
IN MY OPINION ,
to me, my SKS stands modified, as a better gun, than the $1100 VZ 58 does
stock. And yes I do own a VZ 58, and I did fire it stock.
