I just put this on my HK 416 .22lr and it fits great! Just as snug as the original. I like the cheek weld of this stock compared to the original. The twist off recoil pad works and is removable for storage. The only slight squawk is that this stock is about 1" longer in the front than the original, so it rides up against the buffer tube nut on the rifle, when in the very forward detent. The locking lever won't fully seat. If you really wanted, you could remove approx. 1/16" or less of material from the front of the stock and it would probably fully lock, but I see no need to do so. All other four positions work perfectly! It seems to be very high quality. I would definitely recommend this stock for your 416 .22lr.
