The AR10 platform does not enjoy a common design between manufacturers, like the AR15.    As a result, there can and will be subtle differences in the parts kits of various manufacturers.  Some parts, like the fire control group, are shared with the AR15 platform to preserve the options for upgrading.  For best results, we recommend only using PSA PA10 parts with our uppers and lower receivers.  We do not recommend using other manufacturers parts in our products.

Introducing the Palmetto State Armory PA10 QMS Lower Parts Kit.

High quality lower parts kit that includes a superior ALG QMS fire control group. The ALG Defense Quality Mil-Spec (QMS) Trigger is designed for those shooters where tradition, value and regulatory concerns are of primary importance. The pull of the QMS is very similar to a standard mil-spec trigger, however the majority of the associated grittiness of the stock trigger pull has been removed while the well known reliability of a stock trigger remains. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5lbs.

Included is what you need to assemble your PSA PA10 Stripped Lower Receiver, less the buffer tube assembly:
- QMS Trigger Group
- Magazine Catch Assembly
- Front and Rear Takedown Pins, Springs, and Detents
- PA10 Bolt Catch Assembly
- Safety Selector Assembly
- Grip Assembly

This is a bulk packed ALG trigger assembly, it will not have retail packaging. 

The trigger guard assembly is not needed, since the PSA PA10 Stripped Lower Receiver features an integrated trigger guard.
The safety selector, fire control group, and grip on the PA10 are identical to their AR15 counterparts. The PA10 bolt catch, and takedown pins are different than their AR15 counterparts, and are not interchangeable. Use of AR15 components for the bolt catch, and takedown pins are not recommended, and may void any warranties.

Good kit great trigger
Installed this in a PSA lower everything's fit and finish seems great. Makes sure you degrease and clean the parts real well before you install or you may have some binding issues. Very nice trigger for the price point—worth the upgrade. My only complaint it that the the Bolt Catch touches/rubs up again the PSA upper receiver marring the upper's finish.
