RAVEN barrel, 6.01mm, XM177, M4A1, SG551, 375mm, PDI

Precision steel 6.01 mm inner barrel PDI series of RAVEN for type of weapons XM177E2, M4A1, SG551, M15A4 Carbine/TC/RIS/SPC and M15A2 Carbine - 375 mm. Very accurate and hard steel barrel STKM13C. Steel barrel has undergone a specially made process, which also leads to specific dark color. It is an accurate surface coating material which in the final product corrosion resistance and also a very high hardness. As stainless steel is mainly PDI also made this technology of cold forging, which is also used for manufacturing the barrel of guns. This is the precision production with Japanese manufacturing tolerance of +/- 0.007 mm.

Internal precision barrel is part of the upgrade, which together with the appropriate Hop-Up bucking significantly affects the accuracy and partially overall performance/range weapons. The smaller inner diameter, thus inevitably results to better tightening of BBs. At the same time, however, higher demands for regular cleaning and using only quality airsoft BBs (we recomend BBs from BLS). Otherwise, it may lead to a reduction of muzzle velocity as well as accidental or "choking" of weapons. If you choose a barrel please do not make a decision only according to the inner diameterand the lowest price. An important factor is also the procedure and method of production, the type of finishes, materials and the manufacturer and whch country it was made.
