- Get Your LARP On: Inspired by the cheek risers used by high-speed guys in the 80’s and 90’s. The paper and steel targets at the range will appreciate your range-day drip. - Style 1 Original vs Longer: Style 1 ( Original / Cherokee ) will allow use of the charging handle at every position except fully collapsed. Style 1 (Longer) goes .75" further forward on the stock and must be two or more positions out to allow the charging handle to be fully pulled back. - Color Options: Available in Black, Earth Brown, and Forest Green - Secure Fitment: Notched rear slides over the raised portion of the CAR 15 stock. The nub inside the riser then fits into the circular hole on the top of the stock. This dual interface system ensures a tight fit without slop. It may take some force to get the circular nub to fit into the hole on the top of the stock. It should not require any tools, just some muscle.  - Sight Compatability: The height of these risers will make the iron sights unusable. They are intended for use with an optic on top of a carry handle. - Original Design: 1900+ products designed and 3D printed in the heart of America in St Louis, Missouri by Hammy3DPrints.   NOTE: This will not fit the BKF CAR 15 style stock.   - Installation: For Styles 1-3, slide the rear of the riser down and over the circular part of the stock first. Then, slide it back as far as it can go, ensuring that the raised portion of the stock goes into the notch on the back. Then, push the front of the riser down firmly. If the riser is not seated, continue pushing down and back on the riser until the circular nub seats into the hole on the top of the stock. For Style 4, put the front of the riser on first. There is a cut-out on the front that the front of the stock rests into. Once that is in place, push the back of the riser down over the stock. Ensure it is fully seated by trying to rock it side to side and pushing it back and forth. It should be solidly locked in place.
