Product Description The Area 419 Universal Weight-Tunable ARCALOCK Rail is a precision-engineered, 14.25-inch rail system designed for serious rifle shooters who demand versatility and performance. Since the introduction of the ARCALOCK system in 2018, this mounting solution has become a staple in the precision shooting community. This universal version is anticipated to fit approximately 98% of Manners PRS1, T2A, T2A GAP, T4A, T4A TEAM, and T5A stocks, making it one of the most broadly compatible weight-tunable rails on the market. Machined from aircraft-grade aluminum with a sleek black anodized finish and featuring five included brass tuning weights, this rail allows shooters to dial in their rifle balance with precision. The bare rail weighs just over 6 ounces, while each of the five brass weights adds 3.5 ounces, bringing the fully loaded rail to approximately 23.6 ounces. Every corner is radiused and every edge is chamfered, eliminating sharp points for a refined, shooter-friendly design. T-nut hardware is included to add attachment points if your stock&';s factory-installed mounting points do not align with the rail&';s mounting slots. Proudly 100% made in the USA.
