Took my new build for a spin at Atterbury today. The upper is 16" stock 450 ar Bushmaster and the lower is a polymer hybrid by Omni to keep down weight. Shot a box of ammo thru it. It reminds me of 12 ga duck loads. Not as bad as 12 slug but more than muzzy. Muzzy on steroids! With a good shooter and better shooter, I think it's capable of inch or inch and a half groups at 100 yds. Overall I'm pleased with it. I'm also happy to report that the polymer lower has not cracked.   |

Good group!
I wouldn't be worried about the lower cracking.
If you think about it the lower really doesn't take that much abuse.
Now just need to get the upper Cerakoted and you will have one really nice looking AR!

Now just need to get the upper Cerakoted and you will have one really nice looking AR! I'm too cheap and old for Cerakote. The gun only has to 44 more years (till I'm 100). I have thought about dipping at in ASAT but I'll likely stick with rattle can and wrapping. Gonna be a working gun not a show dog! |

What rounds are you shooting? Mine likes the Hornady Custom 250 grain, and works great on deer and hogs (and probably anything else you'd shooti with it).
Also, are you still using a mil-spec trigger? I put a Timney in mine, but I've put together a couple other ARs since then with Rise Armament triggers that I like just as well. The trigger is what made the biggest difference in my accuracy with the gun.

The trigger is what made the biggest difference in my accuracy with the gun. Hornady 250 is what I used. I have mil spec trigger that's been worked down to 4-5 lbs with lighter springs. It's ok for hunting. How much and how many pounds is the Armament trigger. One thing I've now realized is that the last shot hold open on the chamber is not working on the Omni lower. I'm not sure how important it is to me in a hunting situation. |

I believe it's 3.5 lbs, I paid around $120 for mine a few years ago. They feel as good as the Timney in my .450. |

When you pull it back by hand with a empty mag in it dose it work then? I had another ar bolt catch to compare to. Used a drimel to file down the non-working one to match the other. Everything works well now as far as I can tell without shooting it. Wonder if my kit had a bolt catch from an a10? |
