The GI 100 rifle by PTR Industries has a very unique look. With its Parkerized finish and classic green furniture (polymer handguard, fixed stock with sling attachment, and grip wrap), this Rifle is sure to catch some looks. The GI 100 also features an 18" tapered barrel and a classic "SEF" steel lower. PTR decided to remove the precision-welded top rail on this GI 100 to allow the use of original claw mounts and carry handles. If you've been looking for a modern rifle that has a "classic" design, look no further that PTR's GI 100 .308 18" Rifle. Note: The 18" tapered barrel accepts 5/8x24 threaded barrel accessories.
