Ak-100 Series Trunnion

The left-side folding stock trunnion and hinge mechanism is available separately from the folding stock for the first time. This hinge mechanism comes standard on the Arsenal SLR-106F and SLR-106FR (4.5mm pivot pin) series rifle. It is required when installing the new left-side folding solid polymer stock onto a rifle not previously equipped. The installation of the folding stock mechanism is best performed by a qualified gunsmith if it will be installed on a receiver without the proper cut-outs for this type of folding stock mechanism.
