Please advise. I already own a stripped receiver, so I'm planning to spend $700 and buy a M4 rifle kit with the following features: Barrel - 16" M4 - 1x7 Twist - Chrome Lined + $45 - 5.56mm Lower Parts Kit - River Rock Arms 2 stage trigger + $80 Handguards - CAR Handguard with Heat Shield-Black Gas Block - Standard A2 Front Sight Grip - A2 Grip Flash Hiders - A2 Flash Hider Charging handles - Standard Charging Handle Buttstock - M4 Buttstock Bolt and Carrier - Standard Bolt and Carrier Upper Receiver - M4 Feed Ramps + $25 I'm thinking of going with Del-Ton because the total cost for the kit would be $635, ($659 with shipping). Though, I've never heard of this company before, so I'm cautious about buy from them. I chose these two brands because the were the least expensive. I would be open to go with at different brand if you guys think I will be making a mistake.
