PRE-ORDER Guidance

As you are probably aware, recent updates to ATF's eForm approval process has resulted in drastically improved turnaround times. While this is certainly a positive change, it has also had a predictable impact on suppressor inventory across the industry.

With that in mind, if you know you want a particular suppressor (or three) and it isn't in stock, your best bet is to place a "PRE-ORDER" so that we can purchase your desired suppressor the moment it becomes available from our distributors. If you wait until it shows in-stock on the website, you might miss your opportunity. PRE-ORDER helps us seek out and purchase what you are looking for. This is true whether you buy from us or someone else.

Thank you for considering Longbow Arms, we hope to earn your business.
