Trigger plate components

) # REMINGTONFIELD SERVICE MANUAL The Model 740 is an autoloading,high power,center fire rifle.To operate the autoloading action,a measured portion of the pro-pellent gases are exhausted from an opening at midsection of barrel as gun is fired.This gas drives action bar assembly rearward,carrying with it the bolt carrier.The bolt carier is attached to bolt by cam pins which work in cam ways in bolt.The cam ways areso cut that a delay occurs between the time action bar begins to move rearward,and the time bolt starts to rotate.This delayis timed to permit bullet to clear muzzle and chamber pressure to reduce,before bolt begins to rotate from a locked position. The replacement of barrels and breech bolts requires selective assembly.That is,special tools and gauges are used to make certainthe rifle will operate correctly.Allother replacement parts,or components,can be assembled as received,but since they are madeto close dimensions,the particular part may need slight adjustment to be sure rifle will operate correctly.An effort has been madein this manual to anticipate and describe such necessary adjustment. CAUTION:Make certain the firearm is unloaded.Check both magazine and barrel chamber for live cartridges before servicing orshipping firearm.
