WARNING! Before starting any operation on gun, make sure that the gun chamber and magazine are UNLOADED
and the safety is engaged!!
B. Barrel Installation (See Diagram D). With the bolt installed per the Benelli M2 manual, lock the bolt in the open
position. Make sure to clean and re apply blue (Medium Strength non-permanent) 242 Loctite or equivalent on all
threaded areas. 1. With barrel at an angle enough to clear XRAIL System barrel clamp area, re-insert the barrel far
enough so taper of barrel is narrow enough to lay barrel flat into XRAIL System Barrel clamp area. 2-3 Once barrel is fully
inserted you can start installing the barrel bracket clamp. Place barrel clamp bracket on (bottom of bracket is tapered to
the barrel - put large taper radius towards receiver). 4. Insert 4 screws and tighten. 5. Alternating side to side, tighten
side angle set screws located closest to the end of the barrel; this will center the barrel over the XRAIL System Outer
Housing. 6. Tighten side angle set screws closest to M2 receiver. 7. Tighten side set screws.
Do not over tighten any fasteners, max recommended tightness is 25 inch lbs (approximately ΒΌ turn once screw is set).
A properly tightened barrel should be centered over the XRAIL System. The barrel should not touch the XRAIL System
from the barrel clamp area to the end of the barrel. Clamping system is adjustable. By tightening, point of impact shift
is possible.
