This is certainly the hay days for AR building. Good Deals are to be found all around.
I took the DelTon Lower and parts kit I won as a door prize at our recent FT Campbell area ARFcom dinner and set out to build a 300 Blackout SBR.
I got a stripped Anderson upper from AIM for $39.99 along with an AAC buffer spring for $2.99
Then I ordered a 8.5" barrel for $79.99 and a NiB BCG and CH for $119.99 from Palmetto State Armory
I ordered a MI 7" gen 2 SS free float handguard for $135.95 directly from Midwest iIndustries since they were as cheap as I could find anywhere else and they were throwing in free handguard pannels with it. I added their upper parts kit for $19.99 to qualify for the free shipping on orders over $150.
Then I picked up a (new) AAC 51T blackout FH here on the EE for $60 shipped and ended up getting a CTR stock in FDE from the same guy (new in box) for another $50.
I picked up the mil spec buffer tube, locking plate, castle nut, YHM low profile gas block, pistol length gas tube and an FDE ergo grip from my local shop for $70 out the door.
I already had an extra carbine buffer and a mini red dot at home to finish it out.
Grand total out of pocket on this was $581.88
If one really wants to build a no frills basic M4 type carbine right now they could probably do it for around $500 if not a little less.
Now with e-filed form ones taking 4-5 weeks for approval I should be able to have mine built and running by Christmas.
