Oversized Merchandise Shipping
Oversized merchandise (Flat screen LED TVs over 55", plasma TVs over 51", BBQ Grills & Furniture) are shipped via a motor freight carrier that specializes in Home Delivery. Since these items are large and fragile, special handling is required, and cannot be shipped via our standard shipping options.
We take every precaution during our shipping preparation process to ensure that your order arrives to you in perfect condition. Each item on your order is scanned for accuracy of model and serial number. We apply large orange fragile sticker labels to notify the carrier that your shipment is fragile and requires special handling. The labels also include important step-by-step instructions on how to inspect and sign for your shipment. In addition to the manufacturer's standard foam and corrugated packaging, we also apply a special shock absorption polyethylene material to the outer carton of every TV. This safeguard will disperse energy from impact during transit, and eliminate damage to the product itself. Our professional appointment-based delivery service allows you to open and inspect your new TV prior to signing and accepting the TV. When you purchase a TV at Beachcamera.com, you can be sure that it will arrive perfect working order, and will remain that way for a long time to come.

Product Details
Magpul MBUS Generation II Sight Set Front & Rear Color Black
Product Description:
The Magpul MBUS (Magpul Back-Up Sight) Gen 2 Front & Rear Set is the industry-standard flip-up backup iron sight for AR-15/M16/M4-platform rifles — a matched pair of lightweight, durable, injection-molded polymer sights that provide a reliable secondary aiming system when your primary optic fails, runs out of battery, or gets damaged. Trusted by military, law enforcement, and civilian shooters worldwide, the MBUS Gen 2 has become the default backup sight recommendation for the AR platform because it delivers proven performance, effortless deployment, and rock-solid durability at a price that makes running without backup sights inexcusable.
The MBUS Gen 2 Front Sight (MAG247) features a spring-loaded flip-up mechanism that deploys instantly when activated from either side — press the ambidextrous release paddles or push the top, and the sight snaps upright with positive detent engagement that keeps it locked in the deployed position. The spring-locking A2-style front sight post is adjustable for elevation using the included sight adjustment tool or any standard A2 sight tool, providing the same height-over-bore as standard military A2 iron sights. Protective wings on both sides shield the front post from impact damage during hard use, drops, and rough handling. When stowed, the front sight folds to a profile of approximately 0.51 inches above the rail and 2.6 inches in length — low enough to sit beneath most optics without interference.
The MBUS Gen 2 Rear Sight (MAG248) features a dual-aperture design with both a large aperture (for close-range and low-light shooting) and a small aperture (for precision aiming at longer distances), both on the same plane for consistent point of impact. The windage adjustment wheel on the right side provides tool-free horizontal corrections in the field — rotate the knob to move the aperture left or right without needing tools, a significant advantage when making rapid adjustments. The rear sight uses the same spring-loaded ambidextrous deployment mechanism and detent-locked erect position as the front sight, and folds to the same ultra-low 0.51-inch stowed profile.
Both sights clamp securely to any MIL-STD-1913 Picatinny or STANAG 4694 receiver rail with no tools required beyond a standard cross-slot screwdriver or hex key for the rail clamp. The sights provide the same height-over-bore as standard A2 iron sights, making them compatible with absolute co-witness or lower 1/3 co-witness setups with red dot optics — deploy the MBUS sights and your red dot's point of aim aligns with the iron sight picture, providing a seamless transition if your optic goes down.
Magpul's impact-resistant polymer construction provides an exceptional strength-to-weight ratio. The detent and spring pressure system keeps each sight firmly erect when deployed but allows unobstructed folding under impact — if you bang the sight against a doorframe, barricade, or vehicle, it folds flat rather than breaking or bending your rail. The entire set weighs approximately 2.3 ounces combined, adding virtually no weight to your rifle. Made in the USA.
