Thank you all for your input. I will forward this thread to others here in the company for review.
Now I will answer these points where I am able:
Properly staked gas key with proper fasteners YES
FA carrier chrome lined YES (with the exception of NY, NJ, CT, MA we ship AR carriers in the compliant weapons for those states. Still chrome lined)
Individually tested bolts (shot peened) and barrels Barrel steel is MP tested. Bolts are HP/MP tested and shot peened. Still not sure about individual or batch, waiting on the cert from our supplier
11595 barrel steel or 249/240 MG steel or proven (Noveske) stainless, 11595E barrel steel.
Standard profile 1/7. 1/7 14.5 M4s being made now and soon to be released. 1/7 20A2s will be available in the near future
5.56 chamber Yes
Lower parts kit in equal quality to Colt, or at least LMT/BCM/DD YES. I don't know if a picture proves anything but here's one to examine anyway for those interested
Staked castle nut with milspec diameter extension NO, we leave the staking up to the customer to decide. If a customer wants it factory staked he can call customer service and send the lower in and we will do it at the factory at no charge. Buffer tubes are commercial spec but we are in discussions about offering mil-spec tubes
Correct buffer for gas system YES? It's the same buffer that I've been installing in AR15s for the last 13 years with no issues (previous company)
All holes drilled to spec, including gas ports appropriate to gas system length. Here are our gas port sizes:
14.5"––––––––––––-.067"
16"––––––––––––––-.063"
20"––––––––––––––-.093"
When we start doing 11.5" they will be .076".
Standard or MOE stock/handguard/grip 6 position tele stock, standard A2 pistol grip
M4 feed ramps. YES
Correct height FSB Front sight bases are not F marked. If a taller post is needed we carry +.040 front sight posts in stock.
