So the "new guy" over at Woodcraft mistakenly made a batch of plastic slider pucks that were just a touch too small. Normally 50mm around, these bad boys come in at 47mm. They are 100% perfect, except for that pesky 3mm. Gives us 3mm and we will save you $15! We liked this deal so much we bought hundreds of kits so we could offer this deal up to our STG Customers. Click on the image above for our Woodcraft Frame Slider category on the site, shoot Jimmy a PM on the beeb or send an email to email@example.com if you need a new set of frame sliders and like saving money. Thank you for all of the support, our first month here has been a good one for sure!
