This B4 PDW by Bolt Airsoft is designed for melee combat environment and also keeps realistic recoil feelings with their BRSS system for AEG in place. 

With the new designed M-lock plastic handguard, PDW stock, and short silencer, PDW AEG is more convenient to carry and also with precision shooting performance. Bolt Airsoft joins a bit late to the PDW party, but glad they also provide this option now out of the box!
