ModulusArms's Achievements



  1. No, universal as in capable of finishing off any AR15 lower either forged or billet. There is no .308 AR15, .308 is an AR10 and is a totally different receiver. The AR10 jig is larger in order to fit the bigger AR10 receivers and is not interchangeable with any AR15 jig componenets
  2. Take a look at the forearms from MI before you decide. Excellent quality at a decent price. especially their gen 2 SS series http://www.brownells.com/rifle-parts/forend-amp-handguard-parts/handguards-amp-rails/index.htm?avs|Make_3=AR-15zz1zzM4&avs|Manufacturer_1=midwest%20industries%2C%20inc.
  3. Very simple to install, they even include the wrench.
  4. I like the one used in this thread. http://ar15armory.com/forums/topic/154893-another-one-down/
  5. Very nice. I really like the midwest industries gen 2 forearms, I've used those on the last two ARs that I put together. Solid, high quality piece and it wont break the bank.
  6. Flash hiders are illegal in MA. You must use a compensater or a brake.in MA and it must be permanently attached (pinned, welded or silver soldered) in order to be legal.
  7. I have a few ARs with high end triggers in them including triggers from Jewel and Accuracy Speaks. I put a Giessele in a rifle I built recently, I like it as much as any AR trigger I have ever shot. There will be more in my future.
  8. If you build enough of them, eventually You will run into a combination that will not HS correctly. It has happened to Me twice. The most recent was about a year ago. I bought a BCG that would not close on a go in the build I was doing. Turned out that this brand new BCG would only HS correctly in 2 of the 5 ARs I tried it in. I ended up using it in one of those two, which was OK since the BCG I took out of that one spaced correctly in the new build I was doing.
  9. I will exchange it no problem if that's what you want. We don't do local sales anymore so it will need to be done through shipping. With that said, it is not chips in the hole. The white powder comes from the anodizing process. It is basically just aluminum oxide powder in the hole. It gets cleaned during anodizing but occasionally some of them have more then others and this can happen. It's very rare. All you would need to do is use some water or spin a drill bit in your fingers like someone above mentioned. It would come right out. Many other lowers on the market have shorter spring detent holes and you actually need to cut the spring for it to fit.
  10. Gone until next year!
