I am considering both the PLR 16 as well as the RDB bullpup for an HD gun. Both of them have their design advantages, and one has a price advantage (actually the RDB is cheaper than a Tavor, so that counts as well), but my main concern is reliability. Anyone have experience with these two. I did not like the PMR30, very finicky with ammo, so I am more careful with Keltec now. Thanks for any advise.
