I have a Spikes Calico Jack and an Anderson (Bushmaster) lower.
I have a Bushmaster stripped upper. I have noticed that there is more slop or slack when it is on the Spikes lower. The fit is better when it's mounted on the Anderson lower. Is this normal? Is it better to match the upper and lower? Thanks! |
