I`m helping one of my buddies from Canmore build a Modern Sporter. It will be the first time I have been involved in a build from scratch so I'd like to check that he hasn't missed any parts (he has been busy cleaning his other guns so I'm trying to help out):
We have:
1) ATRS upper / lower set.
2) Barrel
3) Trigger
4) Handguard
5) Buttstock
6) BCG (complete)
7) Forward assist
8) Muzzle brake
9) Pistol grip
10) Mag release
11) Bolt release
12) Charging handle
13) End plate and castle nut
14) Barrel nut
15) JP SCS
By my reckoning we still need:
1) Gas block
2) Gas tube
3) Dust cover
4) AR15 Lower pin and spring kit
5) Safety (I know we could get that as part of a lower parts kit but he has a special one he likes picked out)
Have we missed anything required to complete the build? He has lots of scopes and magazines so no issues there. Its a ways for me to get to Canmore so I want to make sure we have everything required to avoid multiple trips.
