The Argos BTR Gen 2 comes with a set of flip-up caps, but here are the Butler Creek sizes:
Objective: 40
Ocular: 19
The sunshade that will fit this model is 214061S.
You can use any Athlon rifle scope with both eyes open.
The Athlon Optics Argos 6-24 x 50 mm Rifle Scope is rated for recoil up to 50 BMG, as well as all Athlon optics that have a 3 letter abbreviation (BTR).
I would strongly suggest using a 20 MOA rail if you plan on using this scope to 1,000 yards. Without having the gun to verify, the educated guess would be to use medium rings from our Precision or Armor ring lines.
I would recommend using one of our cantilever mounts. This will ensure proper height and eye relief.
