This is the HK SL8 stock block to G-36 Conversion, first generation seeing here!

Now a few photos for quality comparison.....

A little explanation, you may see conversions using the G36 pistol grips with full auto pictograms, those pictograms are just for looks and 100% legal per ATF, all installed internals are from the Semi Auto SL8 and selector will not swing pass the semi auto position.

Here is the HK SL8-1 conversion to G-36 - Upper receiver Milling/Dye work

 Comparison of HK SL8-1 and SL8-6 Buffer House

NEW THIRD GENERATION HDPS G36 STOCK BLOCKS HAVE THIS HOUSING MILLED IN THE SAME BLOCK, YOU DON'T NEED USE THE POLYMER HK HOUSING ANYMORE!!!

Some explanations about "Why make it in Aluminum"

I choose the Rapid Prototype part to be clear so it would be easier to see the internal parts attached, it  could be in black or any other color.

For those that wonder if I will sell those parts in "durable" plastic, the answer is "no". Rapid Prototyping is what the name says.... a rapid part, it's used to check dimensions only from CAD files, would be not only expensive for each part but also unsafe to use those parts in a firearm taking the carrier and return spring rod abuse. Sure they look cool in the photo but looking closely they look like they were carved with a kitchen knife. Even the early SL8 itself suffer from polymer cracking problems in the lower receiver...and that's is a space age polymer.

Here is the Fast Prototype for the USC block that was done nearly a year ago, lower hinge crack after insertion of the roll pins a few times, material used was one of the "tuff plastic"

Another reason here, other brand stock block made from plastic come to us for replacement...

So, I decide to do the SL8 to G-36 Stock block in T6 Aluminum like the USC stock blocks are being made. The rapid prototype for the SL8 that you are seeing here do not reflect the final looks of the part, it was just to check if the dimensions were right.....the final product will be very nice looking one and those that are waiting will be very pleased.

1- If you are seeking any conversion that involves removing the barrel from your SL8 receiver, I will not accept the last batch (2010) of HK SL8-6 receivers that has the serial number also engraved in the barrel. Even using the proper tools (Mandrel and Barrel Nut) to remove the barrel nut sometimes is very hard or impossible to  slide the barrel out of the receiver as in this last batch for some reason everything is too tight, way beyond from Hk own specifications for torque per HK G36 Armorer's Manual.

2- take a look on your hammer first.
