Hight Road,
I have just bought a new RRA CAR A4. If I wanted to purchase a new full upper (say one with a 20inch), will that go with my lower? I understand this may be a basic question. Just curious if a gunshow rolls around, and I see an upper I like, will it be compatible with the RRA lower I have now.
If not, why and what do I need to look out for?
Thanks, Dave
