CG Jackson trigger on Quadlite

[nickj890]

I've tried various searches but with no luck, I know this has probably been covered given the age of the action and trigger combo.

I have a Quadlite action purchased around 2002 that I have fitted with a CG Jackson trigger made for a Rem 700 or clone. The Quadlite includes an accessory hanger bracket to allow the use of Remington pattern triggers in place of the RPA blue trigger it included. I have also in the past tried a Jewell trigger on it as well.

While the CG trigger is great, like the Jewell it seems like both allow the firing pin to partially de-cock when closing the bolt. By that I mean that the firing pin does not seem to be held back as far as designed and falls a shorter distance when released. I have experienced the occasional fail to fire with both CCI and Federal primers on a 6 BR it is chambered for.

Looking at the shape of the cocking ramp on triggers made for a Remington you can see that they are sloped where the cocking pin on the Quadlites bolt is straight.

Is there a modified cocking pin or other change that anyone has performed when using a Remington pattern trigger on a Quadlite?

I know that the CG trigger I purchased for my RPA 2000 included instructions and drawings on how to modify the RPA cocking pin for use with the CG trigger.

How much firing pin drop do you get when you close the bolt? A small amount isn't unusual. The Quadlite has a short pin fall but makes up for it with a huge firing pin spring. Changed the spring lately?

Is the trigger hanger for the Quadlite like the trigger hanger for a BAT. Can it be turned around for a different trigger timing?

I haven't measured the FP drop yet, just an observation that when you open the bolt, the rear of the striker is visible in the hole in the rear cap on the bolt and is flush. Then when the bolt is rotated shut, the rear of the striker drops slightly as well as you can feel it de-cocking for part of the rotation of the bolt handle.

Reversing the trigger hanger is a great idea I never checked to see if it had an offset.

Thanks for the suggestions.

Nick,

Received your PM and I will lengthy reply to it shortly.

Regarding the Quadlite, the FP travel is 4mm (.157) as colmpared to the .270 of the Remington. As Blair says, this not only need a specific spring (or better a set of Belleville washers), but the FP travel is not to be reduced.

I would tend to think the problem comes fron the hanger?

If the FP travel is not sufficient, perhaps you could elongate the fixing holes in order to move the trigger unit backwards in order to use the ful intended FPl stroke. I think a very little filing (maybe .008 to .012) will be sufficient?.

The Remington trigger sear lever and the FP sear are angled because of the trigger sear lever is articulated at front, and need this slope to permit disengage from the firing pin sear.

There was in the past 2 C.G models made with this buttress lever principle, the ones for Remington 700 and the CG-RPA 2000 and Quadlock. This was the reason why it was advised to slope slightly the FP sear pin to ease the release by rotation of the triggersear lever (that we named the 4th lever).

All the future models to come shortly ‘redesigned and made in USA” will be without this buttress system and will function perfectly, FP sear sloped or not.

Hppe this will help?

Sincerely

Robert,

Thank you for your reply and explanation. I will have a look at the potential for re positioning the trigger hanger to correct the timing issue.

Thank you again to all who replied!

Nick,
I had a similar situation with the same set of components. What I found was the hanger positioned the trigger low in relation to the firing pin sear. This causes the firing pin sear to contact the slope of the trigger sear bar higher (and as a result, further forward) resulting in the condition that you describe.
In my case, I machined the trigger hanger to raise the trigger location which cured the problem.
This may or may not apply to your set of components but it is something to look at, hope you find it helpful.

Pete,

I will check that dimension as well. Thanks for the suggestion honestly I never considered that the hanger was the easiest item to modify in order to adjust the relationship between the trigger and the action. It makes complete sense!

Nick,

I have a Quadlite with a CG trigger just as you describe. In fact I purchased it from Mr. Fiori who responded to you yesterday. I am not sure if I have the rifle that he described or if it's another one that he still owns. I can say however that the trigger hanger on my rifle is not symmetrical. I had the same issue you describe when I first set up the rifle. While trying to diagnose the problem I noticed that the hanger has an F engraved on the side with an arrow. When I turned the hanger with the F pointing forward the decocking problem was alleviated. I hope this might help you with your issues.

ETA: Thinking about it I might have an altered hanger as Mr. Fiori described. Last spring I purchased a Bix N' Andy trigger. It couldn't be used because the hanger mounted the trigger so high the hanger wouldn't touch the receiver. The CG trigger was at a perfect height. I'm not sure why there should be a difference.

Nathan,

I checked the hanger and while it is not marked with an F, it is as you and others have suggested, not symmetrical and does allow for re positioning the trigger fore/aft. That's the good news-however it appears to be installed in the rear most position now so reversing it did not improve things. I also tried reversing the position of the trigger itself within the hanger as well to see if I could stack any tolerances in my favor.

I will have to see what can be done to modify the dimensions of the hanger further to adjust the position of the trigger rearward another 1mm or so. Based on viewing the position of the firing pin collar through that vent (?) hole in the side of the bolt body it looks like I am de-cocking the FP approximately 1-2 mm as the bolt rotates into the closed position. I have a line on another CG trigger for a Remington which I might purchase and try as well.

Just in case, this was one of the batch that had the firing pin hole manufactured off center, but I had that corrected via a bushed firing pin hole 2 years ago.
