CMC Tactical Single Stage Trigger - 1TA-TRA-CARSSTG-91503

Written on Jan 15, 2018

I purchased this CMC trigger for a SPR build. It is crisp with very little pre-travel. I have CMC's and a Timney in my other rifles, and for the money. the CMC is an excellent choice. The trigger comes with anti-rotational pins that cinch up with screws on each side. I had zero play or movement inside the lower receiver, so the trigger felt positive in every way. At the time, no one had them cheaper than Optics Planet.

Tacfire AR15 Buffer Detent Pin

Written on Jan 15, 2018

Great option if all you need to finish a build is a buffer detent and spring without purchasing a parts kit. Was happy to see that Optics Planet sold this as a single item. Installs and works flawlessly. Great price!

Si Buffer tube

Written on Jan 08, 2018

Great product! I really like the extended detent tab. Makes for a secure install. Tube comes with a castle nut and endplate with variable sling mounts. I didn't use this piece and went for a simpler QD endplate. 7 positions for a bit more versatility.

CMC AR-15 Single StageTrigger

Written on May 24, 2016

This trigger installs in minutes and comes with its own anti rotation trigger pins. I opted to use KNS pins instead. The CMC has a wide trigger that provides a positive feel that works great for tactical purposes. Extremely crisp and predictable trigger pull. I have a Timney 3# installed in my SR556 and I have to say even though the CMC doesn't have the fancy anodized billet housing or the cinch down screws that take out any play, its just as crisp with very fast reset.
