"Selecting ammunition for your CCU (text from Mech Tech)

There are certain factors to consider when selecting ammunition for use in the CCU's. The CCU is a 'blow back' type action. The main design element in a blow back is the weight (mass) of the bolt. This must be chosen to anticipate the 'hottest' loads encountered. The physics of a blow back action is such that the bolt mass and the bullet weight (mass) work together to limit the amount of the case which is allowed to move out of the chamber while the bullet is still in the bore. When the round is fired two things happen immediately:



1) the bullet begins to move out of the case mouth and up the bore
2) the case begins to move to the rear pressing against the breech face.


To elaborate, the case acts like a piston pushing out of the chamber to the rear and the only thing limiting the amount of movement of the case is the mass of the bolt - contrary to popular belief the recoil spring plays a negligible role in the initial case movement. The real design issue is to limit to a safe value the distance over which the case moves to the rear out of the chamber over the time that the bullet is still in the bore. As long as the bullet is in the bore the gas pressures are high and the case must have sufficient support to prevent case head blow-out or other pressure signs. The bolt weight in the CCU is enough for a good safety margin and as such the ammunition needs to be powerful enough for reliable ejection. 'Target' loads generally are not 'hot' enough. One should use the hotter factory loadings especially in 9mm where a +P loadings are best. "


This CCU and the Glock 21 SF Lower are NEW and unfired. The range that I belong to doesn't allow long guns other than .22LR. I couldn't persuade them that a lot of pistols being shot there have way more velocity and energy than this .45 with a 16" barrel. I won't drive 30 miles to another range to shoot this carbine.

The CCU with the monorail, 3-rail front mount, front clamp-on sling mount, and telescoping stock cost me $602.35 delivered. I bought the M4 Stock Conversion Adapter for $33.45 , the IMI Mil Spec M4 stock(with wrench, spring and buffer) and rubber butt plate cover for $81.

I got the Glock 21 SF Lower for $311.25 + $25 FFL fee. The cheapie red/green dot sight cost me $50.

I added the Ghost 3.5 lb connector, an extended slide lock, and extended magazine release to the G21 SF lower for $30. I'll round up the original parts and include them, too.

This all adds up to my cost of $1,133.05, not including the Korean-made 27-round magazines. 5 of those cost me $100, but they can be had cheaper these days, bringing my total to $1,238 so far.

My FFL shipping cost will be about $50, so the total is up to $1,288.

For Sale, shipping included. $1,100 Cash or Money order. For credit card/debit card, add $35. I have to pay 3.5% for CC use.
