Lets talk safety:
The FX Impact MKI and MKII both have issues with chamber flags...
Trying to go to the range or a competition where a range master might require you to clear your chamber?
Well it was a bit difficult to do that with the Impact before now. Chamber flags are designed for mag wells or larger chambers which the Impact has neither of.
Both the red flag and red anodized block machined to fit the Impact will ensure your rifle meets safety requirements and etiquette while you and others are down range.
This design also ensures you aren't shoving something into your barrel where it might damage or nick something.
Neat. Does this fit the crown or is it custom to the impact?
