JP GMR-13 in excellent condition for sale. The rifle has less than 700 rounds through it and is like new. This GMR-13 does have the fully adjustable trigger and the silent captured spring. Also included with the gun is the JP gun case which has never been used and it has been kept in the box since I have other padded gun cases I use to take my rifles to the range or competitions. $1,300.00 or best offer.
