Tariel Posted September 27, 2010 Report Share Posted September 27, 2010 I finally got some good pictures of the original 21E and I mapped out the dimensions using a G3 receiver and its lower with the pictures. I'm going to be cutting and bending out this piece on sheet metal, after which I'll finish with welds, hammering and drilling. I have the equipment along with an anvil which will be my work horse for this. Here's the picture. Hopefully, I succeed without any mess ups. Link to post Share on other sites

aznriptide859 Posted September 27, 2010 Author Report Share Posted September 27, 2010 Drake, for that one how would you do the feed mech? And can you make me one? :D:D Link to post Share on other sites
Tariel Posted September 27, 2010 Report Share Posted September 27, 2010 The feed mech on the old 21E is detachable, it has a retainer on both sides on the front that hold the feed mech with a pin insert. The welder comes in with this since the retainer welded on lol. The feed mech I feel will be the easiest part because it has to be hollow to allow the internals to fit, it'll purely be aesthetics. In case you were asking me how the BB's will feed, I'm going to leave it like any other G3 in airsoft feeds. Don't worry, once I make my first prototype I intend to produce this as a full gun for all. I can't guarantee real deal accuracy on it, but it'll be damn close. For sure what I will design will put Marui to shame with their G3 body design. I'll make sure it doesn't flex or wobble, perhaps I should add blowback? Oh the ideas.. Now I'm not a fan of hi-cap winders or electric feeders, so I was just considering making the box mag one big mid cap. I feel it should be able to hold at least 600+ rounds double stacked with a box that big. Link to post Share on other sites
aznriptide859 Posted September 27, 2010 Author Report Share Posted September 27, 2010 Have an idea - I'm going to purchase the manual for the Hk21E off RobertRTG (I think it's like $10), then scan all the pages and use that as a semi-visual guideline for parts and whatnot. How does that sound? EDIT: Also to people who've modified CETME kits to G3's - are you able to attach the RS stock pin adaptor (the metal part at the front part of the stock) to normal G3 AEG bodies, or do you have to transfer the wood stock to an airsoft stock adaptor?

Tariel Posted September 28, 2010 Report Share Posted September 28, 2010 Damn if you get that manual, it'll become a gold mine to me. Link to post Share on other sites

You can but a bit of it has to be cut so it can fit on, not a big deal really. Link to post Share on other sites
aznriptide859 Posted October 2, 2010 Author Report Share Posted October 2, 2010 Cut where? Do you mean sand it down a bit to fit the body? Link to post Share on other sites
Kenworth W900 Posted October 2, 2010 Report Share Posted October 2, 2010 I'm trying to ascertain exactly why youy want the real steel end cap info... My hope is that its because you are attempting to fit a real HK21 stock, cus that would be epic. Link to post Share on other sites

Tariel Posted October 2, 2010 Report Share Posted October 2, 2010 That stock is a bit pricey to modify wouldn't you say? Well pricey to buy in general, but if you do get it, I want dimensions! Link to post Share on other sites
aznriptide859 Posted October 2, 2010 Author Report Share Posted October 2, 2010 I believe it's $80 without the buttplate, $120 with - not that much lol. Link to post Share on other sites
Azulsky Posted October 2, 2010 Report Share Posted October 2, 2010 Okay so i attached a file depicting the cross section of the g3 stock cap u should be able to know what i am talking about even if it is MS paint Link to post Share on other sites
aznriptide859 Posted October 2, 2010 Author Report Share Posted October 2, 2010 ^That makes sense, so the RS internal tangs that slide onto the body are too wide, correct? Link to post Share on other sites
Mat Posted October 3, 2010 Report Share Posted October 3, 2010 Definitely possible and a great project, I've seen a few and one was for sale over here a while back. the VFC/GBTech version has never appeared despite rumours every so often. I look forward to seeing your results http://www.youtube.com/watch?v=tBMq6LsBgEA Link to post Share on other sites
aznriptide859 Posted October 3, 2010 Author Report Share Posted October 3, 2010 I saw that - that one is pretty impressive, expect the box mag could have looked better lol. I'm most confused by the carry handle mount, the entire barrel shroud, and the bipod - I have no idea how those would go together Link to post Share on other sites
Kenworth W900 Posted October 3, 2010 Report Share Posted October 3, 2010 I believe it's $80 without the buttplate, $120 with - not that much lol. Where from? EDIT: Found it, NVM. Link to post Share on other sites
Mat Posted October 3, 2010 Report Share Posted October 3, 2010 As you may have guessed by my signature, I have a small interest in H&K... so I figured I'd share this item from my collection with you. http://rapidshare.com/files/422847873/hk_11.pdf Link to post Share on other sites
Tariel Posted October 3, 2010 Report Share Posted October 3, 2010 I'm most confused by the carry handle mount, the entire barrel shroud, and the bipod - I have no idea how those would go together Imagine if you will that there are three parts. The body, the front end and then the bridge between them. The bridge goes over the body first and then is welded to it, then the front end goes into the bridge and gets welded to that and the main body. The bridge has the slot on the left side of the gun for the carry handle. The one shown in that video isn't the correct one, but the guy did an impressive job on the gun regardless. If you need references showing this better, I can provide my library to you. As far as the bipod, the iron sight and the bi-pod holder is one piece, that gets put in front of the front end and welded. Link to post Share on other sites

As far as the bipod, the iron sight and the bi-pod holder is one piece, that gets put in front of the front end and welded. So, basically the barrel shroud is built onto the upper reciever first, then the front barrel/cocking assembly is put on that? To my it seems that the area the shroud welds to the front sight post is where the bipod mounts. Have you managed to find a suitable alternative? The Hk21 bipod is friggin $250 >.<...and there's no way I'm spending that much on that stupid part lol. Link to post Share on other sites
Tariel Posted October 3, 2010 Report Share Posted October 3, 2010 I'm making everything from scratch, a mix of welds, cuts and bends with pipes, sheet metal and rods is the way I'm going to have to do it. So far it's comming out pretty good, you're going to have to be innovative and inventive to get the looks and the functions. Otherwise you will be paying a pretty penny for all of it, take your sight for example, or the stock. I'll be making it for a fraction of the cost, sure it'll take work but thats work I don't mind doing. Link to post Share on other sites
