Fitment & Compatibility
How do I know a part will fit my rifle?
Every product page includes a Compatibility & Fitment section along with full specifications covering the platform, mounting interface and any model restrictions. Fitment can vary between manufacturers, generations and build tolerances, so if you're unsure, contact us with your rifle's make and model before ordering.
What is the difference between M-LOK and Picatinny mounting?
M-LOK is a slot-based system where accessories bolt directly into the handguard, keeping the profile slim and the weight low. Picatinny (MIL-STD-1913) is a raised rail with cross-slots that accessories clamp onto. Many accessories are made in both versions — check which interface your handguard has before ordering.
What does Mil-Spec mean for buffer tubes and stocks?
Mil-Spec and commercial receiver extensions have slightly different diameters, so stocks are not always interchangeable between them. Product pages state which fit is required. If you don't know which your rifle uses, measure the tube or ask us.
Can you help me choose the right component?
Yes. Our UK-based team can help match parts to your platform and intended use. Tell us what you're building and we'll point you to compatible options.
Legal & Compliance
Do I need a firearms certificate to order?
It depends on the specific item and your circumstances under UK law — accessories and furniture such as stocks, grips, slings and rail attachments are treated differently to controlled component parts. If you're unsure what applies to a product you're interested in, contact us before ordering and we'll confirm.
