I bought a CZ 452 Trainer a couple of years back and have never really done anything with it. My wife bought me a Boyd's Tacticool for it at Xmas so I decided I would overhaul the rifle this year. I have worked all but 4 weekends since we went back to work after Xmas leave. Now that the weather is getting better, and I have two free weekends in a row, I decided to do some stock work on this rifle. Honestly, the stock was adequate as is. They seem to be scaled at about 7/8 to the full size (which I used on a smokeless muzzleloader last year) but I had a system I pulled off another stock and wanted to use on this one. I bought a McMillan on sale from them that was inletted for another rifle I was building but had an ADJ LOP kit on it. I don't need the ADJ LOP on that rifle and the butt pad was a Pachmayr Presentation pad which was inadequate for the recoil that rifle produces. That meant that I could just install the ADJ LOP on this rimfire so that my nieces and nephews could shoot it short and I could shoot it long. Top is a Boyd's Tacticool (grip reworked to mimic McM A-Series, forearm slimmed down) on my muzzleloader and below is the McMillan A3 after I pulled the ADJ LOP kit from it. A 1" Decelerator will bring it back to correct length: This is what came on the gun. It is not like the stocks I shoot most (McMillan A3, McM Game Scout, Manners T6A, or Boyds Tacticool) so it had to go: CZ 452 Trainer in Tacticool prior to cutting (pad pulled off): Boyds' Pad next to McMillan pad and LOP kit (the shape of the toe is different and the Pachmayr pad on the McM LOP kit is larger over all): The LOP kit has 1.5" of adjustment and a total length of 1 7/8": I taped the stock to prevent chipping (laminates are extremely "chippy" if you have never worked with them) and cut 1 7/8 at a 2° pitch: One thing I have found with Boyd's is nothing is ever straight or flat. Here you can see the old screw holes for the recoil pad in relation to the centerline. If you look at the toe line it is beveled from right to left: [img]http://i1225.photobucket.com/albums/ee394/7mmfreak/20150315_1400481_zpskr6nekhr.jpg[/img]I taped a level to the comb to get a fix on height and used a brad nail to pin it in place so I could mark new holes for mounting hardware: [img]http://i1225.photobucket.com/albums/ee394/7mmfreak/20150315_1416501_zps3y8rbq5l.jpg[/img][img]http://i1225.photobucket.com/albums/ee394/7mmfreak/20150315_1416281_zpsujflsmtt.jpg[/img]Pad is now level with comb and the heel has a gap that must be filled: [img]http://i1225.photobucket.com/albums/ee394/7mmfreak/20150315_1426411_zpsl7cebksf.jpg[/img]

Toe doesn't match but since the toe is beveled anyway I will strip it and build it up: Since the toe has to be built up I drilled holes so the stock has 1/4" toe out: Before view of ADJ LOP Kit before reworking the stock: LOP will be 12.375" to 13.875": I originally picked up this threaded bushing at Lowes to install the stock hardware. Don't use one unless you are going to bore out the hole and just bed it in place. It's head stripped and I had to drill it out of the stock and use a larger bushing: Bushings epoxied in to the stock and waiting to cure (you can also see at the heel where it was stripped and hit with a Dremel to roughen it and ready it for build up): I built the toe and heel up with Bondo: [img]http://i1225.photobucket.com/a...ds/20150321_150009_zpshfoh8d5q.jpg[/img]It has a working time of 3-5 minutes so the first layer went on en mass: [img]http://i1225.photobucket.com/a...ds/20150321_170537_zpsyminorw0.jpg[/img]I worked it down with a rasp to rough shape using a line traced around the pad as my safety buffer and used a straight edge to QC my work: [img]http://i1225.photobucket.com/a...ds/20150322_102317_zpsmkjhac7d.jpg[/img]

I pulled the screw studs they provide and prepped the stock for an Atlas rail. I leveled the stock in the vise then leveled the rail. I then scribed the location for the new holes for the Atlas rail: Once I get the holes drilled out I will attach and bed these brass bushings into the stock to use as the point of attachment for the rail: I then spot drilled all the old swivel holes to get rid of the paint so they could be filled and sanded down smooth. I also drilled the new holes for the Atlas rail:

Forearm stripped and sanded with brass inserts for Atlas rail. Old swivel studs filled and sanded to match: Threaded inserts for cheekpiece epoxied and sanded to match: POW/MIA Kydex Cheekpiece (.080" thick): The McMillan is less steep and the action is farther forward but I reduced the Tacticool as best as possible to match: [img]http://i1225.photobucket.com/a...ds/20150329_130454_zpsxv0jv8bz.jpg[/img]

Excellent post! I've been redoing a shotgun stock with bondo, rasps and files. I can really apreciate the time and effort it takes to stop and document the work. Do you have plans for the leftover stock? I may be interested for my kids.

Very nice work!
Most folks don't really appreciate how labor intensive it is until they try it.

Thx, guys. No progress, I've only had 6 weekends off this year and last weekend we had to celebrate my wife's B-day. I think I can get it painted this upcoming weekend but I need to practice for a rifle match I'm shooting on the following weekend.

Bringing this one back to life to see if there are any further pictures! Won't complain if there are none, as my shotgun stock remains untouched in the shadows.

Did the old stock get sold off? I still have the factory stock. It's on my lonely parts shelf. I usually post all that stuff in the classifieds one or twice a year yard sale style. PM me if you want it.

Sponxx, I was gone from Feb to Jun this year and I'm slammed right now. I still need to bed and paint the stock. I've got about 8000 rounds of ammo that needs to be shot and can't wait to do it. I just need some time off.

Finally getting back to work on this. I had a lot of parts from DIP on back order that finally arrived. I always do "before" and "after" testing so I mounted the DIP 25MoA base and an SWFA Super Sniper 6x for testing. I had 100 rounds of CCI Quiet-22 I wanted to burn up since it is only 750fps at the muzzle. These are the 25m groups. Groups at 50m were about an inch and took 2.5mil from the 25m zero. Groups at 100m took 6.5mil from 25m zero , were about 3 inches and was mostly wind as elevation held at around an inch. I kept the other box for post bedding testing.
