Got the Green spring thinking it was the standard power for a carbine tube. Turns out it's the standard power for the A5 or rifle length tube.
I'd like to trade this Green spring for-
Sprinco White or Blue spring.
Geissele Super42 Carbine spring, or Kit (I'll add cash for the Super42 kit).
3) Keeppower 18650 3500mah or 18350 1200mah high discharge batteries
4) Steel QD endplate- Griffen, bcm, Icw.. etc.
5) Quality H1 buffer
Would sell for $15 + shipping.
Email or IM comms.
