Davidson Defense "Rhino" AR-15

Featuring Aero Precision Upper Receiver

18" .450 Bushmaster 1-24T 4150 CMV Heavy Barrel 

Premium 15" M-Lok Handguard

(Assembled or Unassembled)

The .450 Bushmaster Is The One To Choose Among The 3 Big Bore AR Calibers: .450 Bushmaster, .458 SOCOM, and .50 Beowulf.

.450 Bushmaster Bullets Have Better Ballistics Than .458 SOCOM, And Bushmaster Ammo Is Cheaper And Much Easier To Load. With The Beowulf You Need To Take Out A Mortgage To Pay For Ammo. So, You Choose--Which Caliber Is Better?

This Kit Features An Aero Precision XL Engraved Upper Receiver With An Enlarged Ejection Port To Reliably Cycle The Larger Shell Casings. The Upper Receiver Does Have "XL" Laser Engraved On Top Rail. Forged From 7075-T6 Aluminum, This Stripped Upper Is Precision Machined To Mil-Spec M16/M4 Specifications And Features M4 Feedramps. Match This Upper With One Of Our AR15 Lower Receivers For A Solid And Dependable Fit.

This Build Includes An XX-Treme 4150 CMV Manganese Phosphate HBAR Barrel Chambered In .450 Bushmaster With A 1:24 Twist. Accurate & Powerful.

This Trinity Force 15" Premium KeyMod Handguard Allows You To Comfortably Grip Your Rifle From Various Shooting Positions & Securely Mount A Variety Of Accessories. Made Of Aircraft Grade 6061-T6 Aluminum. This Handguard Comes With Two Quick Detach Sockets, And Is Finished With A Hard Coat Anodizing.

With a Helius Tactical 1776 Series 5/8x32 DTT Custom Edition Black Oxide Finish.

Machined From 416R Stainless Steel & Finished With Black Oxide, The 1776 Large Bore Muzzle Device Is Designed To Work With .450 Bushmaster, .458 SOCOM, & Other Large Bore Calibers. This Muzzle Brake Helps Reduce Felt Recoil And Muzzle Lift By 30%, Which When Dealing With Large Bore Calibers Is Almost Essential. This Brake Is Engineered To Improve Accuracy By Dispersing The Gasses, Reducing Barrel Rise. This Enables The Shooter To Get Back On Target Faster, Which Is An Added Benefit When Hunting To Make Sure You Can Take Home The Prized Beast And Not Settle For Second Place.

The DTT Custom Edition Features The Helios Tactical Laser Engraved American Flag Along With Our Very Own Delta Team Tactical Logo.
