Maple shieldbow (sighted)

The Maple longbow (sighted) requires 45 Ranged to wield, and is obtained by attaching a Longbow sight to a regular Maple longbow. Right click option dismantle the sighted bow into these parts. By massively increasing the longbow's Ranged attack, bonus by +81 (from +29 to +110), the Longbow Sight makes this the most accurate ranged weapon in the free world. It also fires more quickly than an ordinary longbow, as fast as a composite bow.

The Longbow sight, a reward from the Dungeoneering skill, can be bought from the Rewards trader for 10,000 dungeoneering tokens. According to the 10:1 experience to tokens received ratio, one needs 100,000 Dungeoneering experience to obtain sufficient tokens (approximately level 50 Dungeoneering, assuming no tokens spent).

This bow does not increase ranged damage. For training purposes, a Maple shortbow is superior because it fires faster and has the potential to deal damage and earn experience at a faster rate. In other situations, the longer range and increased accuracy can come in handy when fighting aginst an armoured opponent where the shortbow might miss too often.

The bow can give a ranger an advantage in the combat triangle. An impressive ranged attack bonus of around +100 can be retained while wearing the bow with full rune, giving the ranger melee protection but sacrificing the attack speed of the shortbow. Interestingly, this rune tank build's ranged accuracy surpasses the accuracy attainable with a shortbow. Such a build may remove the need for safespots, or come in use in PvP situations against shortbow users or meleers.

Being valued at 5278gp in the Items Kept on Death screen, the sighted longbow is  protected under many items . This bow is not easily replaceable - exercise caution when ranging with it in Dangerous circumstances (including certain PvP situations) where the longbow and its sight may be lost, or bring less expensive items so it will be retained upon death.

Trivia

 * Although it says on the dungeoneering rewards that the longbow sight is members only, it can still be bought and used on F2P too.
 * It is a F2P-usable weapon, though it can fire rune arrows. Rune arrows being a members' object, this is an ironically useless ability as it can only be utilised on members' worlds, on which members could dismantle this bow and use the sight to create the superior Magic longbow (sighted). Although this would suggest that Jagex is considering on releasing rune arrows to F2P at some point in the future.
 * The inventory image appears to be upside down.
 * The three weapons that surpass the sighted maple longbow in ranged accuracy are the Chaotic crossbow and Zaryte bow, having a Ranged attack bonus of +120, and the Magic longbow (sighted), having a Ranged attack bonus of +140. All three are members-only.
 * Even If you're wearing ranged armour, it's quite easy to trump full rune in any ranger vs melee fight. However, it is important to note that any ranger in dragonhide with a shortbow and a range level close to yours will most likely beat you (due to your armour being relatively weak). One way to avoid this is to carry a shortbow in your inventory. Alternatively, (at the cost of lower accuracy bonus) one can tank while wearing full rune.
