Vortex Sparc AR 1x Red Dot: 

Simple—Fast—Effective—Point and Shoot. When you boil it down, those are the advantages of a red dot sight. And that’s what the SPARC AR delivers - all in a durable, lightweight, compact, and ultra-clean package. Digital rear-facing controls for power and dot brightness offer quick access and are viewable from the shooting position. 2 MOA dot diameter promotes precise point of aim and automatically returns to last dot intensity used when powered up.

Unlimited eye relief and parallax free, the SPARC AR gets shooters on target fast. The SPARC AR is waterproof, fog proof and shockproof for ultimate durability. Unit automatically shuts off after 12 hours to prevent accidental battery rundown and operates using a common AAA battery. Duty rifle, home defense, recreation, the SPARC AR is built to handle all your red dot needs.

Features:

Optical

• Fully Multi-Coated ‒ Multiple anti-reflective coatings on all air-to-glass surfaces increase light transmission.

• Bright Red Dot ‒ Display is highly visible in daylight.

• Brightness Settings ‒ Provides 10 variable illumination settings—the lowest two settings are night-vision compatible.

Construction

• Nitrogen gas purging with o-rings-seals delivers fog proof, waterproof performance.

• Compact and lightweight single-piece chassis

• Waterproof ‒ O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments.

• Shockproof ‒ Rugged construction withstands recoil and impact.

• Hard Anodized Finish ‒ Highly durable low-glare matte finish.

• Operating Temperature ‒ Rated from -4 degrees to +158 degrees Fahrenheit.

Convenience

• Non-critical eye relief for rapid target acquisition.

• 12-hour battery power with auto-shutdown feature to maximize battery life (typical battery life is 300 hours at maximum brightness and 5,000 hours at minimum brightness setting).

May this be swapped out for a 300blk instead of a 5.56?

BEST ANSWER: PSA does not currently offer a 7" 300 Blackout upper. We do have 7.5" 300 Blackout uppers, which you could purchase separately with a Vortex SPARC in order to get a similar set up with that caliber.

Great upper for the price
I have had this upper to the range several times, and put roughly 400 rounds through it. So far there have been zero functional issues (loading, firing, and ejecting). At first I was worried that it might have some cycling problems since it has such a short barrel and gas system, but my worries quickly disappeared. I’m very pleased with my purchase.

This was a steal when it was on sale. Mine shipped quickly and arrived on time. It had no issues going on the aero precision lower I had for it and I haven’t had any issues at all. The vortex sight goes awesome with it. Loud as hell and 5.56 makes quite the fireball out the barrel.
