trdsupragt Posted December 26, 2011 Report Share Posted December 26, 2011 I wasn't sure where to put this, but since it's a "sniper" rifle, or a bolt gun, I thought I'd start here. I apologize in advance for the lack of detailed photos because I am the type of person where once I get started on a project, i won't really document that well until I actually near the end of it. Yes yes, I know, the M40A3 has been done time and time again, but it's a gun that I really like the looks of. I'd been wanting an M40A3 for some time but never thought it was worth it to get a Fortress stock back when they were first released. Most of you, if not all of you, will know that they broke very easily and were ridiculously expensive. Well after the college quarter ended and my winter break started, I decided to finally jump on this project and get started. I started off with a Kart M58 (or M40A1). While it's not the best shooter out there, I'm not a big airsofter so this suited my purposes. I shoots decent and shoots where i want it to go 90% of the time. The part that appealed to me most was the bull barrel. As cool as many stocks look out there, sometimes it just ends up looking oversized when the barrel looks dinky as hell. In any case, here's a photo of the starter. When I bought this gun, it actually didn't have the ugly texture like some have commented on. It was more of a rubbery smooth black and didn't have any texture at all. Here's a photo after cutting the thumb rest area. This was the first obstacle to overcome as I didn't know how to get the ball rolling. Finally some molding of bondo onto the rear of the stock. Now it's starting to look a little like an M40A3? Notes: Currently, I'm only using bondo to get the overall structure and shape of the stock. Once that has been completed, I'll be reinforcing it with sheets of fiberglass mostly around the pistol grip area, as that seems to be the weakest point of the stock. My only reference throughout this project is the McMillan website and scattered photos of the actual M40A3/A5 and other forums of people posting pictures of their own McMillan A4 stocks. Hope you guys like the project so far. Link to post Share on other sites

Geri Posted December 26, 2011 Report Share Posted December 26, 2011 Some help for you: http://www.scribd.com/doc/57790982/m40a3 I'm working on something like that, here it is (prototype): Contact me if you need some help. Link to post Share on other sites
wolfgeorge Posted December 27, 2011 Report Share Posted December 27, 2011 This looks amazing!! What's the base gun? Wolf Link to post Share on other sites
trdsupragt Posted December 27, 2011 Author Report Share Posted December 27, 2011 It's a Kart M58 that was shaped like an M40A1. That's a pretty good looking stock you got there Geri. Not bad yourself lol. I've got some more sanding and a little more bondo to go, but here's the latest photo I've got. It's mostly little nooks and crannies that I need to fill in and fine sand now. Then comes the details like the saddle cheek rest and the stock pad. Link to post Share on other sites
Geri Posted December 28, 2011 Report Share Posted December 28, 2011 If I can give an advice: Paint it black or something dark color before every sanding, it makes you easier to find the litle failures on the surface, then sand it til the paint almost dissappear. Link to post Share on other sites
trdsupragt Posted December 30, 2011 Author Report Share Posted December 30, 2011 That's a good suggestion. I thought about doing that but I just don't like how I have to get the sandpaper all gunked up. But I guess quality of the job would be more important than efficiency.

Geri Posted December 31, 2011 Report Share Posted December 31, 2011 Use waterproof sandpaper and water... It makes your life much easier Link to post Share on other sites
CHIFF_MoA Posted December 31, 2011 Report Share Posted December 31, 2011 Nice work so far trdsupragt, looking forward to seeing this one completed. It amazes me that no-one makes a propper, M40 still. I know there's the tanaka one, but gas isn't really the right platform for a BASR, there really is a gap in the market methinks.

trdsupragt Posted January 4, 2012 Author Report Share Posted January 4, 2012 Thanks CHIFF. As pleased as I am with the project thus far, just the stock alone is rather heavy already. So I'm not sure how field worthy it would be. Then again, I don't even play much anymore.. So I guess that's somewhat redundant. I'm now in the final phases of molding and sanding and getting the little details on the stock smoothed out. Then comes accessories, like figuring out the saddle cheek rest and the stock pad. Geri, what did you use for the shoulder pads? I'm trying to find something that will work for it. Link to post Share on other sites
Geri Posted January 4, 2012 Report Share Posted January 4, 2012 I wil make it from biresin and two component rubber, the cheek piece will be made of kydex. Link to post Share on other sites
trdsupragt Posted January 5, 2012 Author Report Share Posted January 5, 2012 I'm thinking of ordering a set of thumbscrews straight from McMillan and using my own kydex to make the cheek piece as well. Can you suggest which products I should specifically use for the pad? Link to post Share on other sites
Geri Posted January 5, 2012 Report Share Posted January 5, 2012 I prefer the Biresin G26 with black urethane paint, but for the rubber I still have no idea. Where can I buy the original McMillan screws?? Link to post Share on other sites
trdsupragt Posted January 6, 2012 Author Report Share Posted January 6, 2012 I emailed McMillan and they told me to give their customer service line a call, and the people there will send me a set. Though I don't know how much they cost, as I haven't had the time to call yet. New picture. I still need to add some more to the stock as it's feeling kind of uneven. The hook needs work, as well as the ledge where the pistol grip is. Link to post Share on other sites
Geri Posted January 20, 2012 Report Share Posted January 20, 2012 How does it progress? I will make the first one on next week Link to post Share on other sites
Geri Posted February 26, 2012 Report Share Posted February 26, 2012 I made my first today: The next have darker and greener colour And still there are some problems... Link to post Share on other sites
Dan B Posted February 26, 2012 Report Share Posted February 26, 2012 Wow, that's looking really good... What problems are you having with it out of interest? Link to post Share on other sites
Geri Posted February 27, 2012 Report Share Posted February 27, 2012 The colour my largest trouble, but you may see it that on the end of the stock there are little indentures and where the edges of the casting mould meet they moved away from their place compared to each other in some places. To the next I will solve the problems, and sadly will be black, I cannot hit the suitable green colour unfortunately. Link to post Share on other sites
trdsupragt Posted March 13, 2012 Author Report Share Posted March 13, 2012 I had been too busy to finish the stock lately. =[ But now that I am on sprig break, I can get back to work on it a little bit. The hard part now is just picking up where I left off. I just need to remember what I have to do again lol. Link to post Share on other sites

Lajjvo Posted May 23, 2012 Report Share Posted May 23, 2012 Stock looks awesome! Is it just me, or is the barrel a bit too thin? Might be the picture f'cking it up a little? Link to post Share on other sites
Geri Posted May 23, 2012 Report Share Posted May 23, 2012 Yes it's too thin, it's the original M700 barrel, because I still couldn't find a G&G steel barrel... (without fluteing) Link to post Share on other sites
