Homebuilt AR RGuns Upper and CMMG lower

Function testing a home built AR platform I call the ZAR (Zeke’s Automatic Rifle). I heard mixed things about RGuns hardware but I have to say it is well made and performed flawlessly. The CMMG lower has a sticky magazine well and did not want to let go of the magazines. All of the P-mags got stuck but the cheap Thermamold ones worked great. and are an excellent value and great for range training.

  1. Nice video. Did you have any issue with the upper? When I got my upper from R-Guns. I had issue with over gassing. So I bought a adjustable gas block. When I went to change out the gas block. I noticed that the gas tube was held in with a nail. Other than that it shoots pretty good.
