Your choice of GB is fine, I´m no fan of Drop In GB´s but for lower end replacements, D-Boys offers some of the better ones for the minimum amount of $$.
And to back up M14 D-T, he hit the nail on the head with a sledge hammer, D-Boys offers some great base models for tuning, solid bodies, nice workmanship, some good detail.
Sooner or later they will be taking over as one of the best Budget AS Gun companies.
