The Timney Calvin Elite 660CE is a single-stage match trigger for AR-15 and M4 pattern rifles, fitting standard lower receivers through the existing pin holes.
Calvin Elite craftsmanship for the AR-15 — a 1.5 lb (680 g) match break with a shoe you can fit to your finger.
The Timney Calvin Elite 660CE is the flagship of Timney's AR-15 line: a single-stage match trigger breaking at 1.5 lb (680 g), designed by trigger maker Calvin Motley, with a shoe adjustable for reach and position so the trigger meets your finger exactly where your mechanics want it. The break is the Calvin Elite signature — instantaneous, glass-clean, with no perceptible movement before or after.
At this weight the 660CE is a precision instrument for match and range rifles. The self-contained drop-in module arrives calibrated and installs through standard pin holes in minutes.
Drops into AR-15/M4 pattern lower receivers via the existing pin holes — including UK straight-pull AR-15 target builds, where a 1.5 lb (680 g) match break and an adjustable shoe suit deliberate, aimed shooting from a bipod or bench. Confirm your trigger pin size before ordering. A pull this light belongs on dedicated match and range rifles: set up and verify function and safety accordingly before live fire.

£5 tracked UK delivery on every order via Royal Mail Tracked 24. Our products are ordered in from the manufacturer rather than held in UK stock, so please allow 7 to 10 business days (Monday to Friday, excluding bank holidays) from the date of your order for it to reach you. Tracking details are emailed on dispatch. UK delivery only.

Yes, it is a drop-in single-stage unit for AR-15 and M4 pattern lowers. As with any drop-in AR trigger, confirm your trigger pin size before ordering, since that is the usual sticking point on mixed-parts builds. Nothing about fitting it requires machining of the receiver.
The headline is the shoe: it can be adjusted for reach and position, so you can move the face to where your finger naturally lands rather than adapting your grip to the trigger. Combined with a 1.5 lb (680 g) single-stage break, it is aimed squarely at precision and match work rather than hard use. It rewards shooters who care about repeating exactly the same finger placement shot after shot.
It is set up as a 1.5 lb (680 g) single-stage trigger, which is deliberately light and better suited to slow, aimed fire than to fast handling. Because it is that light, take extra care with function checks after fitting and treat the rifle as you would any precision setup. If you want something heavier for general shooting, one of the standard-weight Timney units is a better starting point.
Choose it if you shoot from a bench, bipod or a supported position and want the shoe geometry dialled in to your hand. If you mainly want a clean, straightforward improvement over a mil-spec trigger, there are simpler and less expensive options in <a href="/collections/timney-triggers">the Timney range</a>. Our <a href="/blogs/buying-guides/ar-15-trigger-guide">AR-15 trigger guide</a> sets out how to pick between them.
