An improved bolt carrier for a firearm is provided that improves the overall reliability and performance of the firearm bolt assembly. The bolt carrier includes a bolt with a body having a number of lugs extending therefrom. The bolt includes an extractor recess sized and configured to avoid any undercut of the lugs adjacent the recess. The bolt also includes an extractor pivotably engaged in a recess formed in the bolt. The extractor has a pair nipples on flanges configured to engage a pair of integrally buffered springs disposed on a tapered spring well on either side of a firing pin bore extending through the bolt.
1. A bolt for a firearm, comprising:
an elongate body having a proximal end, an opposite distal end and a longitudinal axis, the body at its distal end having an annular portion about the longitudinal axis defining an inner cylindrical surface and an outer extremity;
the body further including a number of bolt lugs adjacent its distal end extending radially outwardly from the outer extremity of the annular portion, the bolt lugs including at least a first bolt lug and a second bolt lug;
the annular portion of the body having a recess extending radially therethrough between a first recess surface and a second recess surface, the first recess surface extending parallel to a radially extending surface of the first bolt lug, the second recess surface extending parallel to a radially extending surface of the second bolt lug, each of the first and second recess surfaces extending in a respective plane such that the respective planes intersect.
2. The bolt of claim 1 , wherein the first recess surface is coplanar with the outer surface of the first bolt lug and the second recess surface is coplanar with the outer surface of the second bolt lug.
3. A bolt for a firearm, comprising:
an elongate body having a proximal end, an opposite distal end and a longitudinal axis, the body at its distal end having a lug bearing portion defining an inner cylindrical surface and an outer extremity, the lug bearing portion including a number of bolt lugs extending radially outwardly from the outer extremity thereof;
the lug bearing portion having an extractor accommodating recess extending inwardly from its outer extremity between a first recess surface and a second recess surface, the first and second recess surfaces each extending in a respective plane positioned such that the respective planes intersect.
4. The bolt of claim 3 , wherein the extractor accommodating recess extends longitudinally of the body beyond the lug bearing portion toward the proximal end of the body.
