The present invention provides for a firearm including a buttstock defining a first bore extending along a longitudinal axis and a receiver coupled to the buttstock. The receiver defines a second bore extending substantially parallel to the longitudinal axis and in fluid communication with the first bore. The receiver also defines an ejection port transverse to the longitudinal axis. The firearm further includes a bolt carrier disposed in the second bore and movable relative to the receiver along the longitudinal axis between a firing position and a rearward position. The firearm also includes an expulsion device at least partially disposed in the buttstock for flowing air through the first and second bores and out the ejection port as the bolt carrier moves between the firing and rearward positions.

1. A magazine repair system for a firearm with the system including a plurality of rounds and a receiver defining a void with a barrel attached to the receiver and defining a chamber for receiving the rounds; said system comprising: a buttstock adapted to be coupled to the receiver and having an outer surface;a magazine for housing the rounds and adapted to selectively engage the void of the receiver with said magazine including a top portion having a pair of tabs extending outwardly from said top portion for feeding the rounds into the chamber of the barrel; anda guide member attached to said outer surface of said buttstock and configured to reform said tabs when said tabs are deformed relative to said top portion for properly positioning said tabs to permit proper feeding of the rounds into the chamber of the barrel. 2. A system as set forth in claim 1 wherein said guide member defines a first channel and a second channel spaced from said first channel to define a central body between said first and second channels with said first and second channels selectively receiving said tabs. 3. A system as set forth in claim 2 wherein said central body includes a first end and a second end spaced from each other with said first end having a tapered portion for guiding said tabs into said first and second channels. 4. A system as set forth in claim 2 wherein said first and second channels each have an arcuate inward configuration corresponding to said proper position of said tabs relative to said top portion with said tabs being reformed to a correspondingly arcuate inward configuration as said tabs move through said first and second channels. 5. A system as set forth in claim 1 wherein said outer surface defines a recess with said guide member attached to said buttstock within said recess.
