This bundle includes only the unique parts specific to the WBP 5.45 build kits:
SKU:1555 Bolt Carrier
SKU:1545 23mm Trunnion
SKU:1560 Rear Sight Block
If a barrel is needed, we offer one made for the WBP 5.45 kits here
If you are planning to use a gas block combo, AIMS-74 barrels will also work if the handguard retainer notch is moved.
Excellent price and fast shipping as well! The kit has been very well made, with clean and sharp lines throughout. The WBP logo on the Sight block is a nice addition as well. I plan to make a more modern 5.45 style rifle with this kit. Thanks again!
