This 450 BM upper is ready to rock with a included ASC 450 12 round magazine to insure proper feeding.

*NEW* Shore Tactical 15″ mlok handguard is rock sold while still being very light weight.

*NEW* Shore Tactical big foot charging handle.

Features a 16″ Nitride 1:14 Heavy Barrel with mid length gas system.

Topped with a Helius Tactical 1776 brake engraved with the Shore Tactical Logo this is one attractive setup.

Included in the package is a Nitride MPI BCG and standard charging handle.

Each upper is assembled and head spaced by me personally.

100% USA Components!

This upper has substantial recoil so please be prepared.
While I have attempted to weed out any functionality issue with these doing much testing I have found that there variables that may need to be adjusted in order to achieve a perfectly running rifle.
Some magazines will just not function properly and I recommend using the ASC 450 Bushmaster Magazines.
Most lower setups will work with this upper, however I would not recommend using a poly lower with this rig. Adjusting buffer and spring weight maybe necessary.
If you have any questions please feel free to email me and I can talk to you about any upper you might have a question with.
