The m1a1 carbine is modeled after a late production 1944 m1a1 paratrooper model with a folding black wire stock with a "low wood" walnut forearm and pistol grip, type two barrel band, and the same adjustable sights which were actually introduced in 1944.It includes a 15-round magazine and offers the same common features of the 1945 m1 model.Attention to detail has been carefully taken to produce a replica as close as possible to the original inland production including cartouche marks and stampings in the wood specific features of the inland carbine.Metal Finish: BlackAction: Semi-AutoCaliber: 30 CarbineBarrel Length: 18"Capacity: 15+1Safety: Manual ThumbOal: 25.75"- 35.75"Weight: 5.19 lbsStock Description: Side FoldingTwist: 1:20"Barrel Description: SteelReceiver Material: SteelSights: Adj RearBarrel Length Range: 18" to 18.99"Weight Range: 5 lbs to 5.99 lbsHand: Right HandStock Finish Group: BrownMetal Finish Group: Blued/Black
