Well made, reasonably priced and covers the gas tube on a 20" a2 barrel. - Yankee Hill Machine Todd Jarrett Handguard 12.585 Inch Black YHM-5008-TJ

While my initial basis for this purchase was because it covered the gas rail on a 20" HBAR, I appreciate its quality and comfort. Rails are right where one my need them and not up and down the entire unit. The only downside, and Yankee Hill is not the only culprit, is a special wrench is needed to snug the jam nut. Their wrench is also described as for the barrel but as well, but I found a Magpul armorers wrench far superior. One can snug without the special $30 tool, but it would be harder and risk slipping. On the whole, a good rail for a reasonable price. Recommended.
