Jewell Trigger

When I completed the firelapping of my Remington model 700 Police DM one of the major decisions made was to do something about the OEM trigger which released the sear at 5 1/2 lbs. I decided to remove and replace it with a Jewell Trigger 700 HVR (Hunting/Varmint) unit. There is much discussion about modifying the new type Remington factory trigger and civil liability. I’ll just swap the original with a state of the art component, thank you very much.

For those unfamiliar with Jewell triggers, they are considered by the cognoscenti of rifle shooting to be the very finest made. Nothing is spared in their construction; heat treated 440 stainless steel for internals, 330 stainless for the side plates and all internal parts are stainless. The complete high grade stainless steel construction means very little potential for any corrosion.

The optional factory type safety and bolt release (made from 4130 sheet stainless) function “better than the original”. Also offered is a safety that sits inside the trigger bow for those so inclined. Jewell simply recommends a spritz of lighter fluid to flush any crud from the module (if it should get dirty) after each barrel cleaning.
The First step in this component swap is to remove the factory trigger module

Make absolutely certain the rifle is unloaded and remove the bolt. Remove the stock bolts located in the trigger guard. Remove barreled receiver from stock. (You may wish to remove the scope and possibly the mount too.) Make a quick sketch of the location of the bolt stop/bolt stop spring and their inter-relation with the trigger module and place the receiver on a wooden block approximately 1″ high and carefully drive out the rear trigger group pin (located by safety lever) with a 1/8″ drift punch, remove the bolt stop and bolt stop spring.

Next drift out the front trigger housing unit pin located just in front of the bolt and the trigger module will come free from the receiver. Carefully remove it and beware that the sear safety cam is now loose and both it, and the sear safety spring, can be misplaced. At this point I replace the spring and cam in the module and place a small machine bolt through the holes and fasten them with a nut and washer.

The HVR is fabricated as a complete self contained unit or module as I’ll call it. Tthe design retains the sear safety cam and spring and can be removed for a swap to another Remington rifle if required with a minimum of fuss. All of the adjustment screws pull force, sear engagement, and overtravel can be done with an Allen key through the trigger guard without removing the stock.

After thoroughly cleaning and making a visual inspection of the cuts in the receiver for any burrs or irregularities and we are ready to begin installing the Jewell HVR.
This is simply done in the reverse order:

Slide trigger module into place and gently tap in the front securing pin and place the Bolt stop in the slot parallel the trigger cut in the receiver. It is helpful to use a slave pin or 2nd drift punch to hold parts in place and free up a hand. Rotate the Jewell trigger module into the receiver and slip the drift punch into rear hole from the left side. Now for a little Happy-Happy Joy-Joy time.

Place the bolt stop spring coil down into the small cut alongside the bolt stop (Long arm forward and bent leg fitting into the trigger cut), press downwards and slide the 2nd drift punch through to hold everything in place. Rotate the rear of the HVR into place making sure the leg of the bolt release engages the notch in the bolt stop.

Gently tap the rear stop pin into place with the tapered end first until it is just “peeking” through the opposite side of the pin hole. This should leave about .050-.060″ of the pin exposed above the bolt stop. Now that everything is officially reassembled, insert the bolt and carefully function check the unit by loading some dummy rounds or snap caps and vigorously cycling the action with the safety in the “OFF” position. The firing pin should not fall, if it does readjustment may be necessary. Do not try for a benchrest type weight or release! No adjustments were made to my HVR trigger module. (I had requested that Brian Jewell insert the “A” tension spring and set the release weight for 2 pounds before it left San Marcos, Texas.) The installation instructions were carefully followed and after pinning the HVR in place the next step was verifying the release weight at exactly 2 lbs. under load with the Chatillon weight gauge.

The trigger was function/safety checked as specified above, and the rifle taken to the range and fired for effect. Much has been said about release weights on a tactical rifle, and realistically setting them up for no less than 21/2 pounds. I must now wholeheartedly concur with this. At my selected trigger weight the rifle surprised me on more than one occasion while doing stress drills ( Run’N’Gun’s).

These were not Accidental Discharges, I had completely indexed on the stock, slid off the safety, and had a clear sight picture, but the trigger break was just a wee bit quicker than I wanted to get the shot off. (Reality Check : A Combination of increased Blood Pressure/Pulse and Adrenaline from movement and nature of the shooting drill caused an obvious loss of fine motor skills.)

This is just a little too hairy for real world encounters involving innocents, or myopic “shoot on command” protocols. The weight was bumped up to three pounds via 3/4 turns to the Allen screw located in the top center of the trigger blade and all is now truly well and good. There is no need to worry about the adjustments failing, as the Jewell supplied STS screws all have nylon lock inserts.
Once again, State of the art engineering.

If you own a Remington 700 (or similar “cloned” action), wish to dramatically improve the trigger, and will accept absolutely no compromises in function or performance, get the Jewell HVR. Even if it means some overtime at work, or getting a part time job – I did!
