Remington 597 Volquartsen Hammer & Mcarbo Spring Install



Log in to see fewer ads
I've been meaning to get around to this rifle for awhile now.

I didn't want to drop a ton of money into this rifle but I love it and it needs a better trigger so here's an easy 1 hour project installing a Volquartsen Hammer https://www.volquartsen.com/products...-remington-597 and an Mcarbo 597 Spring & Bushing set: http://www.mcarbo.com/store/p/28-Rem...pring-Kit.aspx

OK! Here we go!

Here's the test subject ready for minor surgery, remove -2- 1/8 allen screws the rear one is longer!



Then gently drift out the trigger housing pin:



The trigger housing drops straight down and away from the receiver:



Next with the hammer in the fired position (capture it don't let it fly forward) drift out the hammer pin:





Here's a comparison shot of the two different spring & hammer parts







It was tough to get a shot of it, but here's the best I could do. This is the order of the parts in the trigger group





All done! Going back together:



Bushing then Hammer then Bushing easy! (Spring goes behind the hammer)



While we've got it all apart, loosen the guide rods, it helps!



All Done!

This has always been a fine shooting rifle. Bi-pod 50 yards



Beautiful Morning at the range!



A fun day! (all empty!) Haven't been able to just relax and do that in awhile!

Great pictorial! I just blundered my way through the VQ hammer replacement. Well worth the effort and expense as the trigger is now quite nice. I haven't done the MCarbo spring kit yet as my rifle already has a good trigger, but I am tempted to give it a try. Thanks for the excellent pictures

I also installed the Mcarbo spring and a VQ extractor on mine. I like the improvements. Your write up and photos are great, thanks.

Very well done pictorial! I finally found a source and ordered the vq hammer and extractor. Haven't really had extraction issues but I figured the price is cheap enough might is well get it.

Thanks. I've done three VQ hammer springs but no Mcarbo yet. My last 597 has such a light factory pull I couldn't use a VQ as the pull went down near 1 lb after install. Too light for my taste when hunting. Pics are helpful for reference.

Is the Mcarbo spring a good addition to the VQ hammer?

I know this is an older thread, but thought I'd ask anyway.

I have already installed a VQ hammer into my 597, will the Mcarbo spring/bushing kit further reduce trigger weight?

The current weight is a nice improvement over stock, but I'm a "trigger Nazi" and would like to lighten it further. Assuming there are no issues with hammer follow, light strikes etc.

Odd you mention this. I shoot that rifle quite a bit, And just shot it recently.
That being said, if I had to do it all over again, I’d just go with the Volquartsen hammer and maybe bushings, no reduced power spring.

I love Mcarbo stuff and use many of their products. In this case Remington got this one right. Stock springs and a Volquartsen hammer is the way I’d go knowing what I now know. (I have way way too many 597’s like 8, and this rifle is the only one with more than a VQ hammer.) I’ve never had a light strike though I’m an ammo snob and only shoot CCI Mini Mags and CCI SV.

The trigger (With spring and hammer) isn’t as crip as I’d like it. Oh I also have a Jard on one rifle. Let me say, in my opinion, the VQ hammer is the best all around mod.

FlysAlot,
Thanks for the quick reply, I'll stay with just the hammer.

I would definitely listen to Flys. With that said, I put Mcarbo spring kit and VQ hammer in mine and it is a consistent 1 3/4 lb and feels good. I may have got lucky.

Yes... it'll make something very good into something that is very great!

Vq hammer + MCARBO spring set...

...but keep the stock parts, just in case.

THANK YOU for the kind words! As I mentioned, I've not had any issues with the combo on that AAC rifle, but with -9- 597's I feel comfortable with:


1 Jard Trigger
1 VQ + Mcarbo Spring Kit
and
7 with just a VQ hammer


All have a VQ Extractor's btw

Great tutorial, FLYsALOT!! I've performed this modification (... with Vq extractors) on both of my Remingtons. These two mod kits were made for each other. There's one video on YouTube where the person goes through each stage...no mods to dual mods.

I can't tell you how to manage your weapons...but I'm NEVER changing back to the original and I'll only perform dual modifications using the Vq hammer and MCARBO trigger spring kit together.

Separately, they're good...but together they're wonderful!!


Here's the video you should see!
