Thanks for the tips, folks!

I just ordered a Blackjack buffer for this carbine (as well as one for my SKS...) and a 21lb Wolff recoil spring (along with another 18.5lb recoil spring for my 1911...). They'll be here in a few days - I have Monday off and they should be here then - and I'll have some much improved rifles.

I better stop spending money now, though... shipping is killing me laugh
