The only limits I have on upgrading is trying not to P.O. my better half 😉
That said I bought a cheap gun so I do not expect too much from it .
If it turns out I like to platform I'll most likely upgrade to a better rifle rather than plat the parts game.
I have a way to hold it in my lead sled by the butt stock & delta ring so I will try without the front hand guard and let you know if the groups improve any.
