Tippmann plastic front sight, new for 68 caliber barrels. These are new and never used. Found in a parts box. Not sure how the plastic has held up but I would buy one of these for display only. These are brand new and should fit stock tippmann barrels for the sl-68, the smg-68, the 68 special, pro-ams and others. The Inner diameter is .864. Some have light wear on exterior from kicking around for so long. No cracks. Multiples available, one included.
