Replacement for AR15/AR10 pistol-grip*
Removable and replaceable front and rear straps for a custom fit over multiple hand sizes
Improved ergonomics and positive anti-slip texture on both sides and rear back-strap
Removable inner core holds a reusable 1/2 fl oz. lubrication bottle (oil not included)
Custom waterproof storage of batteries (AA/AAA or CR123A) or spare bolt/firing pin (AR15/M4) is available with optional Storage Cores
Each kit includes three backstrap sizes (S,M,L), two frontstraps (A1 and A2 style), lubrication bottle core, and dual-drive mounting screw
* NOTE: This TYPE 1 Kit fits all AR15/M4's as well as many 7.62x51 variants such as the Aero Precision M5 308, CMMG MK3, CORE Rifle Systems CORE30, HK 417/MR762A1, LWRCI REPR, Mega Arms MATEN, POF P-308, Ruger SR-762, and SIG716.
The TYPE 2 Kit uses taller backstraps for optimized fit with certain 7.62x51 receivers such as the Armalite AR-10A/B/T, DPMS LR308, KAC SR25, LaRue OBR, LMT .308 MWS, Palmetto PA10, and S&W M&P10.
In general, the TYPE 1 Kit will fit most all 7.62x51 AR lower receivers but there may or may not be a gap between the backstrap's 'beavertail' and the receiver. This gap is purely aesthetic and will not affect function.
