Reviews
ATI 5.56x45mm NATO AR-15 Rifle Parts Kit is rated 4.4516 out of 5 by 31.
Rated 3 out of 5 by from Good price, But second set was incomplete The first kit I bought was complete. However, the second kit was missing the safety detent spring. Let me tell you. Finding a spring like that on a weekend is near impossible. You have to buy a whole spring kit to the tune of around $50.00. Just for a $3.00 spring.

Rated 5 out of 5 by from 1-2-3- Rifle First timer at this. Kit was complete. I found a UTube video and things went together real easy. I'm going to try it this weekend. Super price.. quick delivery. Wish there was a kit where I could choose between good, better, best for some of the parts.

Rated 5 out of 5 by from Don't Hesitate to order this!! My wife got this for me for Christmas this year to go with my Spikes lower. She gave it to me early so I could go ahead and carry it in my patrol car. Fit and finish is almost perfect! I had to file a very small amount off the inside of the grip to fit to my lower but the result was a tight secure feeling grip. The unit looks like it was made at the same factory as my Mil-Spec lower. At the range it ate everything I threw at it and shot as good as the shooter (me) was capable of. I am very satisfied to have a complete ar-15 the way I want it at a lower cost than with me LE discount through our police supply. I wont be taking long range shots but I know it will work well when/if I need it!

Rated 5 out of 5 by from Excellent quality I am a type 07 home based manufacturer and am very familiar with the AR platforms. This showed up on time and appears to be excellent quality. Have not shot it yet so I can't say anything there. Don't know if it is normal or just a forgotten part but it did not come with a trigger guard. No big deal as I simply ordered a new one. But be prepared to order one fyi

Used Polish PPS-43 Parts Kit.

Battle tested first during the siege of Leningrad, the PPS-43 is a brutally effective, simplified version of the famous PPSh-41 and regarded by many as the best submachine gun of World War II. The folding stock made it ideal for tank crews, paratroopers and covert "recon" units where the 700 rpm firepower was used to great effect.

You get all the parts for a complete PPS-43 (cut receiver per BATF regulations), except for the barrel. The deal gets sweeter with ONE of the special 35-rd. PPS-43 box magazines. All for less!

Bring history home!

Please Note: This kit does not include oil can. This item does not include the gun sling or cleaning rod as pictured above.
