I wanted a heavy rig for support shooting so purchased a Foundation Centurion for a Vudoo with a 22" MTU barrel. The Centurion had a Vudoo action inlet and a Vudoo DBM bottom metal inlet. With Vudoo DBM bottom metal there should be no magazine fitment issues. There were none with five 5 round, one 10 round and one 15 round aluminum mag. However, there were with 10 round polymer mags. The action screws were torqued to 6.2Nm, the recommended value by Foundation. Only 8 of 25 of the 10 round polymer mags would lock but many of the others seemed very close. So I retorqued the action screws to 5.6Nm and 13 would lock. Finally I retorqued the action screws to 5.1Nm and all 25 locked. What is the dimensional difference due to the different torques? A few mils?
Is it technologically possible to have mil sized tolerances on polmer? Economically feasible for a product selling for $33?
The workaround was simple but expensive, four more 10 shot aluminum magazines. The added weight is no problem, perhaps a benefit for supported shooting. With a NF ATACR 7-35 x56F1, the total weight of the rig is 17.4lb. It is a brute.
