The Ultradyne C4 Flip-Up Rear Sight utilizes Ultradyne's exclusive dynalign sight picture technology for accurate and immediate acquisition. Most BUIS systems utilize a sight picture that is non-intuitive. In such systems, the brain's visual systems are asked to align a circular rear aperture with a rectangular front post shape while simultaneously ignoring the 'ears' that protect the front sight post. Dynalign's circle-within-circle sight picture allows for faster sight picture acquisition. Additionally, the use of a front aperture further reduces parallax effect which makes accuracy less depend on precise sight alignment. Dynalign is a faster and more accurate sight picture than can improve shooting performance. \u003cbr\u003e\u003cbr\u003eThe C4 Ultradyne Flip-Up Front Sight features a purely concentric sight picture with windage and tool-less elevation adjustability. Designed for maximum flexibility, the Dynamount Front Sight is barrel mounted which greatly reduces sight movement compared to free-float handguard mounting. The Flip-Up Front Sight is also indexable to 45 Degrees for offset use, making it an absolute must have feature for competition shooters engaged in 3-Gun shooting.\u003cbr\u003e\u003cbr\u003eThe Athena Linear Compensator is optimized to reduce muzzle rise with gas being vented at an angle and then forward. This sends a lower percent of sound back towards to shooter. By pairing the Athena with the Dynamount Flip-Up Front Sight, users will benefit from the elimination of sight deflection associated with handguard mounting.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003e\u003cbr\u003eC4 Dynamount Flip-Up Front Sight:\u003cbr\u003e\u003cbr\u003e- Purely Concentric Sight Picture\u003cbr\u003e- Maximum Flexibility\u003cbr\u003e- Windage-Adjustable for Zeroing\u003cbr\u003e- Indexable to 45 Degrees for Offset Use\u003cbr\u003e- Includes 10 MOA Dynalign Aperture and Front Post\u003cbr\u003e- CNC Machined Aluminum\u003cbr\u003e\u003cbr\u003eC4 Flip-Up Rear Sight:\u003cbr\u003e \u003cbr\u003e- Purely Concentric Sight Picture\u003cbr\u003e- Maximum Flexibility\u003cbr\u003e- Superior Side-Adjust Ergonomics\u003cbr\u003e- One-Handed Deployment and Stowage\u003cbr\u003e- Interchangeable Aperture\u003cbr\u003e- MIL-STD-1913 Picatinny Rail\u003cbr\u003e- Includes .070\" Aperture\u003cbr\u003e- CNC Machined\u003cbr\u003e\u003cbr\u003eAthena Linear Compensator:\u003cbr\u003e \u003cbr\u003e- Shrouded Timing Nut Mounting\u003cbr\u003e- 416 Stainless Steel\u003cbr\u003e- Ultra-Rugged Nitride Finish","brand":"Ultradyne","offers":[{"title":"Default Title","offer_id":22112387792975,"sku":"338387","price":309.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0092\/7861\/9727\/products\/GS338387.jpg?v=1555757502","url":"https:\/\/green-supply3.myshopify.com\/products\/c4-fldng-dnmt-fldngft-athn-lnr-cmp-5-8x24","provider":"Green Supply3","version":"1.0","type":"link"}
