Accessories for Winchester

Winchester's current long guns include the SX3 and SX4 semi automatic shotguns, the SXP pump action and the SXR semi automatic rifle. The parts here, all machined by Toni System in Italy, deal with three things: how the gun fits you, how many shells it holds and how fast you can aim.

Adjustable stocks for the SX3 and SX4

With a TST stock on the SX3 or SX4 you choose how long the stock is and how high your cheek sits, then the gun meets your shoulder and eye the same way on every mount. Left handers are covered too, thanks to the reversible side plates and QD sling cups. They are drop in replacements for the factory part: Stocks for Winchester.

Tube extensions

Loading shells one at a time is the slowest part of a shotgun stage. A 12 gauge tube extension lengthens the magazine, so you load fewer times, and moves weight forward to steady the gun in recoil. For the SXP pump there are +2, +3 and +4 round extensions, and for the SX4 a +4 round extension. Many divisions limit the number of shells you may load, so check your rules before choosing the longest. See Tube extensions for Winchester.

A red dot on the SXR

For the SXR and SXR 2 rifles there are Toni System mounts in type A, for RMSc, DPP and Docter optics, and type B, for RMR and RTS. The same mounts fit the Benelli Argo and Browning Bar. A small red dot gives a fast, wide view, useful for moving targets, and it weighs far less than a scope on a rifle that is meant to be carried and swung: Red dot mounts for Winchester.

Frequently asked questions

Does the SX4 stock fit my SX3?

No. Each has its own TST stock, listed by model.

Will a tube extension change my handguard?

On the Winchester models here, check the product page for any fit notes. A longer tube moves weight forward but the extensions are made for the factory guns.

Do you ship stocks outside the EU?

Yes, we ship internationally. Delivery costs for your country are shown at checkout.
