Angel Custom CNC Metal "H-Hop" Hopup Spacer For All Airsoft AEG (Set of 2 / Black & Silver)

"I have to say I was skeptical at first how much of a difference this would make but it blew my expectations out of the water. I use a G&P M4A1 and this tightened my groups from 6 inches at 75 feet to 2.5 inches. For only a couple bucks this is a great and simple upgrade to increase accuracy. As a side note take care while disassembling your hopup unit and keep track of all you parts.

"At first I was very septic about this nub but once installed grouping and range increased with a .25 Elite Force bb's

"These are great little nubs for the price.

I had heard that the rubber ones by Angel were kinda "meh" so i got these ones.

Its a great little upgrade if you are looking to significantly increase the accuracy of your gun.
I currently in my 400fps 30rps TM AUG: This nub, G&P Metal Hopup unit, Madbull shark bucking, Marui stock barrel (Not a believer in the TBBs)
I can hit people fairly consistently at around 170-180ft (about a 15-20 foot increase) with .25s and .28s. The reason is that since their is 2 contact points on the bb, the spin is more balanced, meaning it will fly straighter instead of spinning up and to the left or right.

Pros:
-Cheap
-Metal
-Angel Custom
-Very Solid
-Makes your shots dead accurate and dead straight.
-Increases range by about 10-20 feet.

Con:
-Easy to lose. Was planning to install another one in my KWA G36 but i kinda lost the bag it came in (FAIL)
-I have heard rumors on some forums that they wear out your rubbers faster than normal rubber nubs -due to the fact that they are metal and dont press harder into the buckings. I havent noticed this yet, but just a caution.
-May require sanding in order to fit into some hopup units. (a bit wider than normal nubs) I tried to fit in my TM P90 unit and the fit was kinda tight. Just another FYI

All in all, these are some of the best nubs you can get. They great for the price and help wonders with accuracy and range.

Definitely a keeper! 5/5
