H&K SL8 to XM8 Conversion from TommyBuilt Tactical LLC

TommyBuilt Tactical will take that old SL8 in the back of your gun safe and convert it to an XM8 replica.

The SL8 was discontinued around 2011 and is now only found on the used market. TommyBuilt makes a conversion kit and converts the receiver to accept double stack mags along with all the bodywork and laser engraved markings to look more like an XM8.

They tell us it’s an expensive conversion with the market price of a used SL8 along with the parts and labor you typically end up with a $5k to $6k project.

This one has the Spuhr AB STANAG magwell. They chopped the barrel and pinned and welded an AAC QD and then finished in Tactical OD green with Magpul FDE accents. Optic is the Steiner Optics DRS1X.

    Tommy built is also making HK G36 and UMP clones. Pretty cool for a small business!

    That is amazing.

    What’s he going to do for his next trick, build a G11 replica that feeds from P90 mags? ?

      The XM8 uses the same internals as a normal G36. It is basically a new plastic shell for a G36. so not that hard to make. The fancy integrated optics with laser and stuff, that the XM8 was supposed to get we cannot have of course.

    Not only does Tom make high quality (very high quality) clones, he is a great guy too. I’ve talked to him on the phone, and he has done some work for me in the past. He is truly a master craftsman in the glass filled nylon/injection mold industry.
