Frequently Asked Questions
What is the difference between the Open and Standard Division 2011 base pad?
The Open Division base pad is longer than the Standard Division version.
Will this fit STI (or) BUL magazines?
Yes — this fits the STI & BUL 2011 double-stack Open Division magazine tubes in 9mm and .38 Super plus clones.
Should I choose aluminium or brass Open Division base pads?
Aluminium base pads add minimal weight, ideal for speed-focused Open Division setups. Brass base pads add more weight for faster gravity-assisted magazine drops and improved recoil characteristics. Choose based on whether you prioritise speed or weight distribution.
Does this fit SVI or MBX Open Division magazines?
No. This base pad is designed specifically for STI and Bul Armory 2011 double-stack magazine tubes. SVI and MBX magazines have slight measurement differences and need a different base pad, or modifications can be done to make them fit.
How long does installation take on Open Division magazines?
Approximately 2 minutes per magazine. Remove the factory base pad, slide on the aluminium replacement, and ensure the retention plate clicks securely into place. Function test with snap caps before competition use.
