Russian tapco SKS with upgrades

 I have a used numbers matching (except for mag and stock obviously) Russian SKS with some upgrades. Internals are clean with no pitting. The bolt has been shaved, and the mag release had been swapped to the AK style to allow for easier detachable mag loading. The bore is chrome lined. The bayonet had been swapped for a sharpened, shortened Chinese one for better stabby-stabby. The stock is tapco with a cheese grater gas tube cover and angled foregrip. The buttstock was swapped with a magpul one. Comes with one five round promag, but will require fitting to the gun as it's tight. There are scrapes and scratches on the gun throughout as it has been used. Looking for $800 shipped
