Psa Ar15 Pa10 Ept Enhanced Polished Trigger Review

When I saw the KS-47 Pistol from Palmetto State Armory, I thought to myself "now that looks fun!". Afterwards some easily-on time with this 7.62x29mm pistol, I tin can say information technology's a lot more than only fun! In this article I'll requite an overview of the KS-47 platform, give a guided bout of the 8.5″ pistol (also bachelor as a 16″ carbine), reflect on shooting suppressed, evaluate the trigger, and compare ballistics with my 16″ AK Carbine. Let'south get to it!

The Palmetto State Arsenal KS-47 G2 is based on the AR-15 and combines the modular construction, accurateness, and precision of the AR platform with the stopping ability and the magazine options of the AK.  The KS-47 G2 lets the AK shooter capitalize on their inventory of AK magazines and AK ammo with an AR-fashion platform. Dissimilar the AK, where the barrel is permanently pressed into the receiver, the KS-47 G2 features an AR-style modular configuration which consists of a barreled upper receiver, and a lower receiver that houses the fire control group and mag. The modular configuration allows customers to have several different butt configurations with one lower receiver, just by releasing two pins.

TriggerScan Analysis: PSA EPT (Enhanced Polished Trigger)

The KS-47 includes what Palmetto State Armory calls the "EPT" (Enhanced Polished Trigger).

From the Palmetto State Armory EPT product page:

PSA AR15/PA10 Enhanced Polished Trigger

SKU: 507797

UPC: 507797

MFR#: 507797

Nosotros start with our standard single-phase government-mode burn down control group,  finely polish the contact surfaces and then glaze the hammer and trigger in a super slick nickel finish.   The result is a trigger that is substantially smoother than mil-spec.  A dandy economical upgrade.

Here's the KS-47 on the TriggerScan TS-eleven trigger profiling musical instrument:

Equally I e'er practise, I ran three consecutive TriggerScan passes, and produced the following results:

And here's the results:

What's amazing most the EPT is how affordable information technology is- it'south available as a stand up-alone parts kit for around $30.00. Because how consistently this trigger performs, I'd say that's a heck of a deal! v.0 lb summit force is perfect for a run-northward-gun type configuration where a medium trigger pull weight is desired.

Test Shooting Scenarios

For shooting scenarios, I decided to focus on reliability, ballistic operation, and suppressed scenarios. Hither'due south a summary of what I did with the rifle:

• Installed Nikon crimson dot sight, performed quick sight-in
• Break-in
• Function testing with a few different magazines (Magpul PMAG 10 and PMAG thirty, generic steel thirty circular AK magazine)
• Function testing with iii types of ammunition
• Ballistics testing: KS-47 -vs- sixteen″ AK carbine

I did non do any accuracy testing as I plan to include this KS-47 in an upcoming series comparison various 7.62x39mm rifles with each other.

The KS-47 functioned 100% with no malfunctions any. This included 3 different magazines, iii types of ammunition, and three types of ammunition. This also included shooting with the included flash hider, and my SilencerCo Hybrid suppressor. Shooting the KS-47 Suppressed is AWESOME! The course-cistron is keen, and it'southward actually dainty to hear the steel ring loud compared to the muzzle blast. I'm sold!

Ammunition Tests and Ballistics

For ammunition, I selected three types of factory 7.62x39mm ammunition. I feel these selections encompass nearly mutual applications for vii.62x39mm.

TUL-AMMO 122 grain FMJ (economy)

I wanted to include some "typical" steel-cased diggings ammo in this testing because that's why a lot of people similar 7.62x39mm rifles: affordable ammo with the "punch" of a xxx caliber projectile.

Federal Ability-Shok 123 grain Soft-Point (premium)

I know a lot of people that hunt with 7.62x39mm in various rifle platforms. So I thought information technology would be a practiced thought to include some premium hunting ammunition that would be suitable for things like coyote or deer hunting. Federal Power-Shok 123 grain soft point ammunition fits the neb nicely, and has boxer-primed brass cases, so information technology's great for reloading equally well.

Federal American Eagle 124 grain FMJ (premium)

Federal American Hawkeye bridges the gap between the TUL-AMMO and Ability-Shok ammo I used for testing: this 124 grain FMJ ammo is brass-cased, and has a general-purpose 124 grain projectile.

For each blazon of ammo, I shot v-shots through the KS-47, and v shots through my 16″ N-PAP AK way carbine. I used my Caldwell G2 Chronograph to collect velocity data for each test cord. Here's the curl-upwards information from these tests:

What'due south interesting here is how the 8.five″ barrel in the KS-47 attained an average of 92.65% of the velocity produced by the 16″ AK Carbine. That's closer than I would have thought. And that means that this pistol is more practical ballistically than most people would retrieve.

And here's the data visualized as a bar chart:

Summary

I accept taken a liking to my KS-47 8.5″ AR-Hybrid 7.62x39mm pistol. It's compact, powerful, and a great balance between fun and practicality. Here's some pros and cons:

KS-47  Pros

• Price: ~$700 for a rifle like this is a deal
• Compact form-gene
• Near-carbine ballistic operation
• AK magazine compatibility
• Value: great quality and features at this price-point
