My recent suppressor thread got me thinking about dropping a couple of tax stamps when I get my taxes back (assuming i'll still legally be able to own one). But if I get one, I want it to fit under the handguards and be over all length of around 16" inches. 2 questions to start: 1. What handguards between 12-15 inches will have enough room to run a suppressor? 2. Would a 10.5" barrel be about the right size to make this happen? Thanks in advance!
