Triple Your Round Count From 10 to 30!

TriMag™ connects three BX-1 factory magazines standard to a Ruger 10/22 semi-automatic rifle. The patented TriMag™ design does not require any glue or adhesive. It only requires a standard screwdriver or coin to assemble/disassemble in the field or home.

Our design is unique in the way magazines are clamped together with no modifications to the original magazine, or use of glue or adhesives. Ours can be taken apart at any time and a magazine replaced or serviced.

TriMag™ is very popular – it has become a standard accessory for avid 10/22 owners, competition shooters, and recreational shooters alike.

TriMag™ is legal in high capacity magazine ban states. If your magazine is legal, TriMag is legal.

  • Ruger has tested and endorsed TriMag™, selling it under their label.

  • The TriMag™ was featured on the first page of the catalog distributed to attendees of the 2010 Shot Show held in Las Vegas.

  • Ruger BX-1 magazines – the magazine fitting TriMag – are now retailed in packs of three! We take credit for influencing that change!

ADDITIONAL BENEFITS to using an Alangator TriMag™.


  1. uses standard 10 round factory BX-1 Ruger magazines, the most prolific, dependable, and popular magazine on the market

  2. supports the rifle in an upright position on the bench when inserted

  3. shape allows for easier loading of the magazines by simply providing more bulk to hold on to, and a steady platform for the upright magazine when placed on a flat surface

  4. eliminates the frustration of “sticky” magazine removal, an intermittent problem with 10/22 rifles.

  5. enables user to quickly access three different types on ammunition preloaded in the individual magazines.

  6. doesn’t interfere with your forearm when firing as extended magazines are famous for.

  7. Bench firing is more convenient - the shooter doesn’t have to move out of position to change magazines.

TriMag™ is a sales multiplier for your existing stock of Ruger 10/22 magazines. It is also very popular in the high capacity magazine ban states throughout the country.


77/22 magazines don’t fit TriMag™! There is quite a bit of misinformation on the internet about a Ruger design change to BX-1 magazines – NOT TRUE!  If it has a flat bottom and a slight taper, it is a 77/22 magazine!  The 77/22 magazine will work in your 10/22, but if it sits recessed from the standard stock when inserted into the rifle, it is the wrong magazine for your 10/22 rifle!

BX-1 magazines will rock side to side on a flat table; they have a slightly rounded bottom and when inserted, they perfectly fit the shape of your rifle with factory stock.   This is the easiest way to check for the correct magazine.

TriMag™ fits perfectly with BX-1 magazines!
No exception! Please do not blame TriMag for a poor fit and spread your misinformation all over the internet.  For those of you who have, SHAME ON YOU!  Go out and fix your error!  Thank you!

TriMag™ with BX-1 magazines attached will work in your 77/22 rifle.  Give it a try!
