Frequently Asked Questions
Is it legal to convert to CCU back to the original pistol?
Yes. The BATFE recently published a ruling which clarifies this – here is the link: https://www.atf.gov/file/55526/download. There has been a lot of misinformation circulating to the effect that once the pistol lower has been assembled to a rifle configuration then converting back to the pistol constitutes ‘making a pistol from a rifle’ and thereby placing the pistol into the SBR (short barreled rifle) class. Not so. Please see our Forum for even further clarification. It is the first post on the Forum so you don’t have to spend time trying to find it.

Can I shoot .45 ACP ammo in my .460 Rowland CCU?
YOU CAN SHOOT 45acp IN OUR 460 ROWLAND CCU. IT IS RECOMMENDED THAT YOU CLEAN THE CHAMBER BEFORE SWITCHING TO REMOVE ANY BUILDUP WHICH COULD CAUSE CASES TO STICK.
Can I shoot .45 Super ammo in my CCU chambered for .45 ACP?
IN OUR 1911 45acp CCU ONLY YOU CAN SHOOT 45 SUPER ONLY IF YOU SPECIFY AT THE TIME OF ORDERING SO WE CAN INSTALL STRONGER PINS IN THE BREACH BLOCK. THERE IS A SMALL CHARGE FOR THIS UPGRADE.
Can I shoot 40 S&W through my 10mm CCU?
IT CAN BE DONE SAFELY BUT THE CHAMBER WOULD NEED TO BE CLEANED THOROUGHLY BETWEEN THE 2 CHAMBERINGS TO PREVENT POSSIBLE CASE STICKING ISSUES.
If I order accessories such as the Quad rail at a time after I purchased a CCU, can I get the factory to install these?
WE SEND COMPLETE INSTRUCTIONS FOR INSTALLING AVAILABLE ACCESSORIES. IF YOU PREFER YOU CAN SHIP YOUR CCU TO MECH TECH AND WE WILL INSTALL THEM FOR YOU AT MINIMAL COST PLUS SHIPPING.
Can I order a Glock or XD CCU in .460 Rowland caliber?
THE GLOCK AND XD BARRELS HAVE A THINNER WALL ON THE BOTTOM OF THE CHAMBER DUE TO DESIGN RESTRICTIONS. FOR THIS REASON MECH TECH SYSTEMS ONLY OFFERS THE 460 ROWLAND FOR THE 1911 CCU.
How do I remove the Flash Hider (or old muzzle dec)?
- Place the barrel muzzle up in a vee block. the edges of the Flash Hider should rest on the block.
- Heat the Flash Hider with a propane torch. Only moderate heat is necessary.
- Use a wooden or plastic dowel to drive the barrel out of the Flash Hider. NOTE: DO NOT TWIST the barrel or Flash Hider as this will cause gauling and make removal more difficult.
- The end of the barrel can be cleaned with light oil and steel wool.
What kind of accuracy can I expect?
This depends on so many variables beyond the control of Mech Tech that we do not specify a number. The CCU is not intended to be a bench rest rifle but there are many units being used in various competitive sports with great success. There are a number of YouTube videos that address this.
What kind of performance increase can I expect with a 16" barrel?
GOING FROM A 5” TO A 16” BARREL YOU CAN EXPECT ABOUT A 70-290 FPS INCREASE AND A 30-40% INCREASE IN MUZZLE ENERGY. SEE BALLISTICSBYTHEINCH.COM FOR SPECIFIC CALIBER/LOAD TEST RESULTS.
