Ruger Mark IV Bolt Assembly 1 2 3 4 MK I II III MKI MKII MKIII MKIV 22LR 22
Part. Shipped with USPS First Class.
These were pulled out of new pistols.
This is a Ruger Mark IV complete pistol bolt assembly. It was removed from a
new Ruger MK 4 pistol. It includes the firing pin, extractor, and recoil-spring
assembly (all the parts as if it were removed from the pistol during
field-stripping). The photo is of one of the bolts we are selling; the bolt you
will receive will be similar to the one shown in the photos. The bolt is
complete, ready for use in a Ruger MK 1, 2, 3 or 4 -- but PLEASE READ the
IMPORTANT details below if you are planning to use this bolt in a Ruger MK 1,
2, or 3.
Mark IV bolts can be used in Ruger's Mark I, Mark II and Mark III pistols,
including the 22/45 versions, but fitting/gunsmithing work may be required, and
certain functions -- like the bolt-hold open, or safeties -- may not work if
combined with receivers and parts other than those made for Ruger Mark 4
pistols. Please read the following carefully:
If a Ruger MK 4 bolt is used in a stock Ruger MK 1, the safety, when engaged,
will not lock the bolt in the closed or hold-open position. The safety can be
engaged (blocking the trigger) while the bolt is cycled to chamber a round.
If a Ruger MK 4 bolt is used in a stock Ruger MK 2, the pistol will function
the same as it did with its Ruger MK 2 bolt.
If a Ruger MK 4 bolt is used in a stock Ruger MK 3, the bolt will not fit, and
the pistol will not function unless the loaded-chamber indicator is removed
from the pistol first; once the loaded-chamber indicator is removed, the pistol
will function the same as it did with its MK 3 bolt.
This Ruger MK 4 bolt would be a direct replacement ("drop in" part) in a stock
Ruger MK 4 pistol.
This Mark IV bolt would be a "drop in" fit for a Tactical Solutions PAC-LITE
IV™ upgrade barrel/receiver since the PAC-LITE IV is designed to use Ruger®
Mark IV™ or Mark IV™ 22/45™ parts. This Mark IV bolt may not be a drop-in part
for earlier versions of a Tactical Solutions PAC-LITE barreled-receiver; you
would need to consult with a gunsmith if you were planning to use this Mark IV
bolt in an earlier version than a PAC-LITE IV.
Firearm bolts should be installed by a qualified gunsmith or persons with
similar technical/mechanical skills. Please check with your gunsmith about any
intended uses you may have for this pistol part.
