Assembly Instructions Product Description These Zippy spacers designed for the BRS Replicant spacers are made in-house from a rubbery, shatter-proof polyurethane. They extend and protect the handles of the Rep, add jimping, and enable adjustable balance with up to 6x removable tungsten weights per spacer. Because every Rep has it's own personality, the adjustable weights allow you to adapt your Rep to suit your specific balance preference, no matter what build you are running. Features Optionally extend handle length from 5.5 in to 5.77 in (regular extensions), or to 5.65 in (half-length extensions for G10 and JT scales). The half-length extensions with 2x tungsten weights per spacer is my personal favorite setup. Shatter-proof extensions protect handles. Positive jimping for extra grip on ladders and chokers available for flush spacers, and extensions for stock G10, JT, and Hybrid reps. Adjustable balance: Each spacer houses up to 6x removable Tungsten weights which enables you to find the perfect balance to suit your preference. The weights can be popped out with a thin, rigid metal object using the 2 slits at the base of the handle extensions, and can be popped in easily with the tip of a clicky pen. The full-length flush spacers and half-length extensions each house up to 3x removable tungsten weights--the flush spacers have similar balance to the stock spacers with all 3x weights installed. Each extension spacer for G10 scales weighs 0.094 oz empty, and up to 0.222 oz with all 6x weights installed. The half-length extensions for G10 and JT scales weigh 0.071 oz empty, or up to 0.134 oz with all 3x weights installed. The other extension spacers weighs 0.08 oz empty, or up to 0.208 oz with all 6x tungsten weights installed. The full-length flush spacers each weigh 0.04 oz empty, or 0.106 oz with 3x weights (similar balance to stock spacers). For comparison, a stock rep spacer weighs 0.11 oz. The handle extensions were designed to fit flush with: Standard G10 Stock Scales (v2 Extensions and Half-length extensions with jimping) Hybrid Scales (v2 Extensions and Half-length extensions with jimping) JT Designed Replicant Scales (v2 Extensions and Half-length extensions with Jimping) Squiggle Scales v1 & v2 The curvature of the extensions may not line up aesthetically perfectly with the rounding/thickness other scales.
