The trigger housing
, mounted at the back of the rail, is home to safety controls/mechanisms, a string latch, Soft Lok Floating Bristle arrow retainer and scope-mounting rail.
The AR70 is fabricated with a stamped receiver and trigger housing
, with a forged and machined barrel extension into which the barrel is screwed.
After checking to make sure the rifle is empty by cycling the bolt and putting it on safe, the first step involves removing the magazine tube and punching out the trigger housing
Underneath the receiver, the Rise Armament logo is visible at the base of the trigger housing
just in front of the top of the trigger shoe.
While the push-pin system makes the gun very quick to strip (remove the end plate, rotate the trigger housing
down and off, remove bolt assembly from the rear), the screw doesn't complicate things since the forend is seldom removed for cleaning.
The kit includes the frame, a two-piece jig, 3mm drill bit (for the locking block and trigger housing
pin holes), 4mm bit (for the trigger pin hole), large end mill (for the barrel block and excess frame material), locking block rail system, rail module and the necessary dowel pins.
The trigger housing
is molded into the polymer stock, and the trigger itself is externally adjustable.
The research and development took more than three years during a span of time in which Ruger had announced its LCR snubnose revolver that has a polymer grip frame and trigger housing
and Smith & Wesson had come out with the M&P Bodyguard 38 revolver with its two-piece polymer/ aluminum-alloy frame.
Using a hammer, drive in the trigger housing
pin, the P80 front rail pin, and the locking block pin (Figure 12).
Items confiscated include the following: 35 trigger housing
assemblies; 60 upper receivers; 15 batter spring locks; 10 barrel assembly M16s; one rail without barrel; one rail with M16 barrel and suppressor; 15 butt assemblies; 15 buffer spring guides; and five quick-detach scope mounts.
