Not really. Reset and lock time is usually a function of the trigger design not the pull weight. I found on both my PC and regular model that is is possible to shoot fast enough to not have the trigger reset properly. Springs don't really help that but in fact often make it worse because the lighter trigger pull allows you to move your finger faster. Happened on both the 15-22 stock trigger and the RRA trigger of the PC model. Only cure is a faster reset and quicker lock time trigger. One solution that many use is installing a Geissele Super 3-Gun trigger. With an S3G trigger in an AR you can dump a 30 round mag in 4 seconds flat. Not the only trigger that will do that as some like the AT AR-Gold or the Wilson Combat 3-gun.
