The RAP Model 500, Iver Johnson AMAC-1500 and Ramo M600 are all similar in basic design, being different mostly in the shape of the barrel, muzzle brake, and bipod.

区域行动方案的500型，艾弗约翰逊援助雷区- 1500和拉莫M600的都是相似的基本设计，主要是被不同的枪管，枪口制动形状和两脚架。

Just behind the engine, the inventors showed me the barrel-shaped metal boiler which, with its super-efficient burner, explains why they have succeeded where others have failed in attempting to drive planes with a steam engine.

只是背后的引擎，发明家表明，我枪管型金属锅炉，其超高效燃烧器，解释了为什么他们成功了别人有没有在试图驾驶飞机与蒸汽机。

This weapon also had longer barrel, and optional bipod and bayonet mount.

The M249 is gas-operated and air-cooled. It has a quick-change barrel, allowing the gunner to rapidly replace an overheated or jammed barrel. A folding bipod is attached near the front of the gun, though a M192 LGM tripod is also available. It can be fed from both linked ammunition and STANAG magazines, like those used in the M16 and M4. This allows the SAW gunner to use rifleman's magazines as an emergency source of ammunition in the event that he runs out of linked rounds. However, this will often cause malfunctions because the magazine spring has difficulty feeding rounds quickly enough to match the SAW's high cyclic rate.

M249采用气动、风冷原理，枪管可快速更换令机枪手在枪管故障或过热时无须浪费时间修理，机枪下前方装有折叠式两脚架，也可使用M192轻机枪的三脚架。M249采用弹链及STANAG弹匣双重供弹，机枪手在断链缺乏弹药等紧急情况时可向装备M16或M4步枪的步兵借用弹匣来射击，但以弹匣供弹时会因弹匣弹簧弹力太大而射速过高及可能出现故障。
