The basic custom upper conversion features a Shilen Stainless Match barrel with a billet, slick-side, flat-top upper receiver, and a Midwest Industries G4 handguard. Each upper comes complete with bolt/carrier, charging handle and magazine. These uppers can be used with any, un-modified, mil-spec lower receiver. You can switch from .223 Rem. to .25 WSSM in 20 seconds! I use Magpul anti-tilt followers as a standard feature in all of my WSSM magazines. By using these followers, I have increased the reliable capacity of the magazine and enhanced the reliability of the upper.
I am now offering a line of wildcat chamberings based off of the WSSM line! I have dies, reamers and barrel-blanks in stock for: .300 WSSM, and .358 WSSM. The .358 version qualifies for being Indiana big-game legal!

- 24", .25 WSSM, un-fluted upper, complete: 6.5 lbs
Note: The .243 WSSM uppers in the same configuration will weigh .15 to .2 lbs more than the .25
Note: Where all of the Winchester factory loaded ammunition for the .223 and .243 WSSM fit perfectly in the modified AR-15 magazine, some of the .25 WSSM factory loads are slightly longer than will fit the magazine. On the 120 grain power point, I have set the bullet back about .015" and have gotten great accuracy, perfect feed and function without any measurable pressure increase. If you are going to hand-load for the .25 WSSM, the mag-length is not an issue.
