Description: This listing complies with eBay's air gun guidelines found here and I will only sell and ship air guns to buyers in jurisdictions where permitted by applicable laws - http://pages.ebay.com/help/policies/firearms-weapons-knives.html This listing includes two custom breech screws and one high-quality Bondhus ® T8 L-key as shown in the photo, we have a separate listing without the tool for a lower price. WE HAVE A SEPARATE LISTING FOR THE SCREWS WITHOUT THE TOOL AT A LOWER PRICE These upgrade breech screws were designed by Magnum Airpower and custom-manufactured exclusively for us, they are not available from any other source. They are made of 410 stainless-steel heat treated to meet metric class 12.9 with a specified hardness of HRc 39-43. Their approximate tensile strength is 185,000 PSI. They have a T8 Torx-socket and are a direct-fit replacement for the original inner breech screw on all the models they are listed for. They are 3/16" long which is 1/16" shorter than the factory screw, it was made shorter so it doesn't stick as far down into the tube as the original which we felt was much longer than it needed to be. Crosman uses a longer screw that was readily available from an industrial supplier to avoid the expense of having a custom-length screw manufactured, that's also possibly why their screw has a tiny .050" socket that rounds-out easily, it's what was cheap and readily available. Do not over-tighten the screw, snug it down only until the breech is firmly against the tube with no wobble. If over-tightened the threads in the tube will strip first, the screw threads are much stronger. If you hold the T8 L-key by the shorter end and insert the longer end into the screw socket it's a lot harder to apply enough force to strip the threads. BREECH SCREW LOCATION: For Discovery, Maximus, 2300KT, 2400KT and some related models you have to remove the rear breech and rear trigger frame screws, take out the rear tube plug, then remove the bolt handle to push the bolt back far enough to access the breech screw. We suggest putting a tiny amount of medium-strength threadlocker on the bolt handle when you put it back on. They tend to come loose otherwise, you only need to put it on finger tight. The standard Crosman Steel Breech Kit, 13XX and many other models have the screw in the position shown in the photo where it's easier to reach. The following videos cover the Discovery model including how to remove and install the breech. eBay does not allow links to be active so you need to copy the red link and paste it into the address bar above in your browser.
