Tough, high-density synthetic rubber wedge drops into the space behind the takedown pin in the lower to provide tension between the halves and prevent movement for improved accuracy and performance so you shoot tight, consistent groups, reduce mis-feeds, and improve ammo feeding.
- Can be trimmed to accommodate any variation in upper-to-lower fit
- Generally, no modifications required
- This is the fastest and simplest accuracy improvement device for your AR/M-16/M4
- Colour: Red
Dropped into Mark's Norinco CQA with no trimming required, although another installation on a customers' CQA required some slight trimming off the base in order to close the upper - you do need it as tight as you can as there will be some 'settling' over time. We have been advised that they don't fit the Springfield Saint lower.
